Drip Fed Waste Oil Heating is open 24/7 World Wide.
We sell our plans Worldwide.
We build heaters for sale.
 These heaters also operate on Canola oil, or Veggie oil should waste oil be a problem.
This is a totally free heating system the works so simply, I don't know why we haven't been using this system for the last 40 years.
Think of the money we would have saved.
We are saving lots of peoples money now.
It's a matter of lighting it, set the temperature, check it periodically, and turn it off at 10.30pm or what ever time you want or don't.
I hope you enjoy our website:), we could have made one heater for ourselves, and left it at that, but we are not like that.
This is just too good not to share with everyone, and so clean burning, cleaner that those smoking wood fires.

I have just had a comment from an engineer that has purchased the plans, and built one, he said those heaters are AWESOME,
 and was going to build three to heat his workshop, house and garage.
Now that's pretty good comment coming from an engineer.
It's funny, as I have built a few for engineers.

Some of which I don't approve of, have started selling them.

The burner unit has a patent, and copyright, so be very careful if you are going to sell our invention.
These are no toys they can reach huge temperatures in the wrong hands can be dangerous.
We will come looking if customers start coming back to us.
 Do Not Sell Our Product!!
Think of something yourself.

*This website is always kept updated.*
With prices in US dollars with NZ dollars to help our overseas buyers.
Latest Update,: * Friday 3rd July* 10.03pm 2015.*

Two new video's have been loaded down the page showing the work office and the old faithfully heater doing 940F.

Freezing Cold?

Lets face it, you may not want to admit it, but winters here in NZ, It's getting bloody cold.

Some of you reaching -20 degrees , it would be ten degrees warmer in the freezer.

I hope you all have a waste oil heater running full time.

If you haven't got one of these heaters, it's costing you dearly in heating bills.

You don't have to keep on paying for LPG anymore.

Alot of us are doing it just a little bit differently this year.

We are letting the trees grow, makes a change,

 We no longer cut trees down for heating.

Firewood is just too expensive too.

So is Gas 9kg what $35 swap a bottle.

It wasn't long ago, I would take the small bottle to be filled and it cost $6.00 dollars it was a joke, and it would last 6 months. 

Now your lucky if it lasts two weeks.

 And those power companies are keeping us broke.

Not now ha ha.

This is totally free heating system that works and it works so well you will be amazed.

Especially when it's freezing cold, and it doesn't use power or gas

So in a power cut, when normally its wet cold, and extreme weather, this will continue to keep you warm.

We are burning free waste engine oil or canola oil cleanly.

Unlike a fire where you have to feed it all day with wood,

these are just a matter of lighting it and run it all day, and turn off at the end of the day, or just leave it going all night.

If you have drums of waste oil sitting outside your workshop, or it's costing you to have it recycled, & the oils building up, why not purchase a drip fed waste oil heater to heat that workshop or shed or home.

The staff would work quite abit better if you have there working area warm, and so would you. 

Make lots of cents.

If you burnt 20 litres of diesel a day to heat your workshop, say at todays diesel price @ $1.32 per litre, thats $26.40 per 8 hours multiply that by 6 days equals $158.40 for the week, multiply that by 4 months equals $2534.40 , 

So after all those calculations if you purchased a drip fed waste oil heater @ $825.00 it will have paid for itself 3 times over just the first winter, and if you have been paying to get that oil recycled, you will also be  saving there too.

Farmers/ Dairy Farmers

We are having a lot of enquiry, and sales from farmers/ dairy farmers wanting hotwater, for their cow sheds.

Not only to keep the milker warm in the morning, but the free hotwater these produce.

 Our heaters are now being used for calf rearing, for mixing up the warm milk powder.

And kid goat rearing and milking, again for mixing up the milk powder

The most recent heater is being used for water heating for the cowshed. 

You are most welcome to come and check out these heaters and the heat they produce,

Just give us a call to arrange a time that suits.

We at Drip fed waste oil heating, are all slowly cleaning up this earth's waste oil problem, one litre at a time.
non of our oil will ever get into any water way.
We have burnt 205 litres of waste oil, this winter, and approaching the second drum.
We have brought one 9kg gas bottle for cooking on gas hobs.
And 2 for the barbecue.
4-5 years ago we would normally have brought $400.00-$600.00 dollars worth of 45kg Gas bottles by now.
So already we have saved $3000.00 in LPG alone.

The selection of drip fed waste oil heaters, with more being built.

*The water heater on the left was sold today for heating water in a cow shed,

free hotwater. 

The new model box frame drip fed waste oil heater, can be built as burner unit only, or the complete unit as in this image. This one is being built for a customer, we have yet to add small feet and wetbacks today. for hot tube heating.
The pot slides in an out for easy cleaning on both units.

How we operate, is we ask for a 1/3 of the price of heater as a deposit, and the remaining balance on delivery.
From the day you order your drip fed waste oil heater, we keep you intouch with the build all the way through, with progress with reports, and images of how far we have got by the end of each day. The unit takes shape before your eyes. This unit has taken us three days to build, and hopefully will be off to the customer in Christchurch tomorrow afternoon. It will be screwed and wired to a half pallet and the two flues, cowling complete with oil fed line and gloves and thermometer will all be packed inside the pot, and the whole lot will be pallet wrapped with address, and off down South to Matt. Thanks Matt

Done, now ready to light and heat.

Some people ask what do these heaters run on; 





WASTE CANOLA OIL. from your fish n chip shop/Deep fryer


Pretty well any oil.

How it works.

Waste engine oil is dripped into a red hot steel pot, containing the fire, when the oil hits the steel, the oil gasifies or bubbles into a gas, and it's the gas that actually is keeping it running, not a pool of waste oil burning in the pot, in fact when it is in operation no oil is visible in the pot at all, just a glowing white ash and it's this reason why it's clean burning.

The oil is burning at such a high temperature that all of the oil burns cleanly, so no smoke is expelled into the air.

With customers wanting more and more water heating we have had to build larger wetbacks over the total range.

So the new wetbacks now have 20 mm copper pipes running the full length inside the furnace. 

Each pipe will be 800 mm long, we now fit two lengths, giving more volume. This makes it 1metre x 600 mm in wetback. 

Another length of 800 mm long pipe, would service the hot water for the house, and the maybe another two lengths  plumbed in, to service the spa pool heating. This is for the smaller hot pot heaters.

I think these heaters/furnaces would accept up to 6 lengths of copper pipe inside the burn zone.

We have only priced them for 2 lengths.

There is a general rule of thumb that the water will start cooling over 5 metres to the hotwater cylinder, spa or pool.

Although we have people heating swimming pools up to 8 metres away from the heater. Insulated pipes are a must.

These heaters/furnaces operate from 250 - 650 Fahrenheit clean burning as you see in the video's.

We test and test these heaters to make sure they reach the smokeless burning stage..

These websites show you how this process happens.

Waste oil heaters and waste oil boilers produce "free" heat, while also eliminating the burden of recycling used oil. It gets even better; some states in America offer tax incentives to heat your facility with waste oil heaters and boilers!

These waste oil heaters and boilers, are typically fuelled with used vegetable oil, recycled oil, used motor oil or used transmission fluid. Restaurants, auto repair shops, quick lubes and manufacturing facilities generate a surplus of used oil. It is difficult to dispose of used oil. You can tap into this enormous surplus by installing a waste oil heater or boiler today, we have these in stock.

Commonly Asked Questions:

Is it really free to heat with waste oil? Yes, if you can generate a sufficient supply of used oil. This cost is about 1/60th of the cost to run a comparable clean fuel oil heater. Most states have used oil suppliers if you do not generate enough on your own. Used oil prices range from $.50 per litre delivered. Take a look at the cost of diesel fuel oil the next time you are filling up your vehicle. Fuel oil is estimated to cost $1.20 per litre this winter. Crunch the numbers; the payback for purchasing a used oil heater is often less than 1 year.

Where can I obtain waste oil? Used oil cannot be safely dumped into the ground, landfills or waterways. Commercial entities that generate used oil typically pay a recycler for proper disposal. You can purchase used oil from recyclers or buy it directly from the source that produces it for nothing. The most common used oil producers are restaurants, quick lubes, automotive repair shops and factories that use hydraulic equipment.

What is the BTU potential of a typical gallon of waste oil? A gallon of used oil contains 153,000 to 180,000 BTU's per gallon. For comparison, a gallon of propane fuel will produce 92,000 BTU's.

Are there environmental concerns when burning waste oil? Modern waste oil heaters and boilers do not produce odours or smoke. 

The cons: As with any heating device, there are pros and cons. Waste oil heaters can require more frequent cleaning then a traditional clean fuel oil heater. If you follow the manufacturer's installation and operation instructions, you shouldn't run into problems. The money you are saving grossly outweighs the small amount of additional maintenance that may or may not be required. These heaters require the bowl to be cleaned out before lighting every third day, and the flue cleaned yearly, that is the only maintenance required.

Ministry for the Environment 

Used oil: managing used oil responsibly

Used oil is the single largest non-watery liquid waste stream in New Zealand. An estimated 30 million litres are generated each year. This explains why used oil is an environmental problem and provides information on what New Zealand is doing to manage used oil.

Why used oil is a problem

During use, oil becomes contaminated with substances that are hazardous to human health and the environment, including heavy metals and polyaromatic hydrocarbons, some of which are potential carcinogens. Good management is required to ensure effective control.

Up to 20 million litres of used oil is believed to be being burned at low temperature, or used as a dust suppressant on unsealed roads, with or without some prior reprocessing or cleaning.

Low temperature burning of used oil generates significantly greater volumes of air pollutants than alternative fuels such as diesel.

At a national level, the disparity in the quantities of pollutants emitted from low temperature burners compared with high temperature kilns is large. Overseas data indicates that dioxin emissions from the burning of used oil will be low and are unlikely to be a problem in New Zealand.

For more detail on the environmental impacts of burning used oil or spreading it on roads, see the Ministry-commissioned report 'Assessment of the effects of combustion and waste, oil and health effects associated with the used of waste oil as a dust suppressant’.

What to do with your used oil

Check with local garages or your local council [Local Government Online website] for the nearest recycled oil collection facility.

What New Zealand is doing to manage waste from used oil

Used oil recovery programmes have been in place for some years. The burning of used oil in high temperature kilns is good practice environmentally because it deals effectively with contaminants. In some areas, local operators collect oil for low temperature burners (which often do not require resource consents), burning in asphalt plants, and road oiling. An unknown but possibly small quantity of used oil is landfilled or dumped illegally in the environment.

The National Environmental Standards for Air Quality, promulgated in 2004, prohibit the burning of oil in the open or without a resource consent. People who burn used oil must not breach the standards outlined in the air standards.

Voluntary collection of waste oil for use as a fuel has been ongoing for many years. The Holcim Geocycle scheme and the R.O.S.E. scheme have been accredited under the Waste Minimisation Act 2008 as voluntary product stewardship schemes. These two schemes together recover an estimated 33 per cent of the used oil waste stream.

The Environmental Protection Authority (EPA) is drafting a code of practice for the management and handling of used oil [EPA website]. This supersedes a guide published by the Ministry for the Environment in 2000. The code provides clarity with and means of compliance with the Hazardous Substances and New Organisms Act (HSNO Act) controls for managing used oil in New Zealand. For example, only burners approved by the EPA are permitted to be used for burning used oil. A list of approved burners can be found on the EPA website.

Neville's new drip fed waste oil heater complete with wetbacks. Now painted Black. ----->>>>
Collected today Thanks.
Temp gauge to be fitted.

             This is the latest heater built for an engineering company in Hastings, Thanks Shahnan 

    This short video is from Perran Willis of his drip fed waste oil heater he's has made our plans he purchased a month ago, very impressive. 

It looks like your trying to split the atom in your back yard. lol

He said the temperature gauge shattered at these temps. This video should answer a few of your questions on waste oil heating and it's ability to heat water. Love it, may have more images to come. Thanks Perran thanks for the feedback.

We need to hear it going too.

This is our home heater that sits outside in all manner of weather, heating the water in the radiator, has been burning waste oil cleanly infact cleaner than all of those wood fires bellowing out smoke I saw today. Running at 950F buning 2.6 litres of oil an hour at this temperature. we have a new stainless flue for her once I get a break from making your heaters. lol. 

With so many orders for heaters, to be built we have now taken over the garage with drill press, compressor sand blaster Cabinet, drills, grinders and the list goes on.

I want to thank you guys for being responsible for making all this clutter and not having a car in the garage for some time now. Good expensive clutter I must say.

OK It's now May only 1 month until winter when you will be freezing all day. Every thought about lay-by a heater now so you have it in time for winter? Interest free so a good time to look into it. 

Now Farmers.
We have started selling these for keeping calfs & goats warm over winter and the hotwater these produce comes in handy with mixing their milk powder. I wish we had this when I was farming, come in wet & freezing cold after the lambing beat, there wouldn't be anything nicer than a warm shed to mother up lambs. I reckoned those bobby calfs will do well this winter with a little warmth. I think as a Shepherd many years ago now, these would work well for any rearing situation even motherless lambs. 
An it would clean up that waste oil sitting outside that shed in that rusting 44 gallon drum. Winning each way.

I went and popped in on a customer today to check his heater was all going well for him., I meet him in his yard, and asked how' it's going, He said No good, Why I said, He said it's too bloody hot. Now this was in a large workshop and it wasn't even the large heater.  It was ticking along at 450 F and beautiful & warm running clean. Excellent to see the finished product operating perfectly.

These would also be perfect for the patio heater. it would run into the late nights on one tank of oil.
I have just been outside with our waste oil heater and testing the temperature with the laser temp gauge, it read 944 Fahrenheit at the top of the bottle, I could feel the heat easily 3 metres  away from it and mines in a 44 gallon drum, so thats a 6 metre diameter. I would guarantee it would make the party warm all night with no smell or smoke and hey it not costing anything to run so you can buy more beer & wine  for your guests very nice.
I love it, and am amazed when customers talk about other companies waste oil heaters like this;
  Hi, Hamish, i am interested in your units to heat under floor heating in 226 sqm house, plus hot water and spa. What size do you recommend, and what is approximate cost? i already have a Kroll waste oil burner but is it quite unreliable and high maintenance. thanks youll-love-it (266 ) 11:02 am, Sun 21 Jun  

 If you are interested in purchasing one of our heaters or plans, but are unfamiliar with the Paypal system, then please get in contact us, we will endeavour to accommodate you in another way, which suites both parties.

*I'm selling just the burner units, why you ask, well I see a lot of cheap gas hotwater cylinders online for sale, some selling for a few hundred bucks so if we remove the gas system and replace it with a waste oil heater burner unit, that will heat all the water you ever wanted, and for free. I'm looking into it at the moment so I'll be back with what I have found.
I have seen it done on youtube and very effectively. A lot of the gas hotwater cylinders are designed to stay outside which would be perfect for this adaption in fact if you live in Hawke's Bay and have a cylinder you no longer want, please could you get in contact I will collect. I would love it to start on these. However this looks like it would be cheaper running on power with that fan they are using

Some people have the problem where the oil supply is kept in the same room or near the heater, all this will does is warm the oil making it thinner and flow faster. 
You need your oil to kept at a consistent temperature without getting warm, a needle valve will fix this problem, so if you are running the heater outside keep the oil inside the shed or visa-versa stopping the oil supply warming up.

We have heaters in stock NOW.
Got an idea, as we have these in stock, if you pop a deposit of $100 dollars, we will hold it in our warehouse wrapped and palleted, we'll pop you name & address details on it, we will send you a photo of what you have on hold, we will freight it to you (at your cost), when the balance is paid in full. You have 6-8 months to pay for it.
This way you'll be sure not to miss out this winter and you can pop money on it when you can afford to not when you have to. I'm very easy going.

Paul, brought his plans a couple of weeks ago, from this website, and I am delighted to show you his finished heater, he has built in only a few days.

It's running at 350 F and sitting in pride of place in his home in Aussie, really nice job Paul. 

We have heaters scattered all around the world, great to see.

Thanks for your feedback excellent job.

Steve has since purchased this heater thanks all those interested. We will be doing more of these at some stage.

Progress report, Tuesday 29th April.  I have unscrew the bottom plate and removed the gas burner unit, and the pipes to the gas controls on the side, this leaves a cone shaped bottom of the hotwater cylinder as it shows in this image. We  installed the burner unit to underneath the cylinder there's a flue that runs up the centre of the cylinder which is about 90mm with a deflector that sits inside it to direct the heat to the sides of the cylinder making the heating of the cylinder more efficient. This may need removing later. Tomorrow we fill it up with water and light the burner unit and time how long it takes to reach a certain temperature like 60 degrees. The images above is what it now looks like. Certainly not aircraft engineering by any means, but we got it. watch this space tomorrow for the video of it going,
I now need to add legs and mount the burner unit to the surrounding tin then weld a seating area for the bowl to slide in and out. Will get on to that tomorrow.
I don't know if I can somehow us the thermostat  possibly not.
I need to find out the max temps this will take before boiling it and expanding the cylinder past the poit of return. I think the tank is copper, which will be great if I find a leak, it can be soldiered.
 I see a lot of cheap good gas hotwater cylinders online for sale, some selling for a few hundred bucks so if we remove the gas system and replace it with a waste oil heater burner unit, that will heat all the water you ever wanted, for free. This would be excellent for underfloor heating systems  as you have a volume of hotwater to pump around the house and I'm picking it wouldn't take the oil burner long to heat that cylinder up.

I have seen it done on youtube but too effectively. A lot of the gas hotwater cylinders are designed to stay outside which would be perfect for this adaption I will be starting on these soon
Just a thought and I sure it will work perfectly.
Ok have set it alight and tested it. It heated the tank of 110 litres to shower temp in an hour so two hours approx it would be boiling. Excellent for radiators in the home. The heater would operate outside with plumbing entering the home carrying the hotwater to the radiators and back to the hotwater cylinder to be reheated. I fitted a 150mm flue on it and it smoked a bit but still within the allowed amount so with the two lengths that came with it would give it more draw and possibly clean it up nicely. So yes a very successful adaption. It's for sale for $400.00 - $450.00 so please email me should you be interested.  A very reasonable priced hotwater cylinder that runs for free on waste oil.

This is the latest heater above we've built, being tested in the video below.

 We now test every heater we sell, to make sure these operate correctly before going to their purchaser. 

This heater is brilliant If I can say so myself, very clean burning.

You can have it as is, or painted heatproof black up to the purchaser.

For sale as a heater only or as you see it in these two images. $1800.00 

Here stands a 45 kg drip fed waste oil heater, the beast of waste oil heating, suitable either as a workshop heater, or a large swimming pool heater, you decide. 

If it sells as a workshop heater, the price is $1800.00, if we have to add the 20 mm copper piping wetback and brass fittings to make it into a pool heater the price is $2500.00.

This heater comes complete with 2 lengths of 150 mm Galv flue.

A brass needle valve to control it.

Oil feed line able to connect to either a twenty litre container or a 44 gallon drum of waste oil.

Your choice wether you would like it painted heatproof black or as it is, in buffed steel.

Capable of reaching temperatures around 650 Fahrenheit although we recommend it operates between 350 and 450 F Temperature gauge will also be provided.

Should you be interested in this heater please email us at;

* This is not suitable for home heating unless it is installed outside the home and the use of hotwater is used to heat the home. These are designed for heating inside of a workshop. These are to big for the domestic house.

It is available as a heater today, however as a pool heater we would need a week to complete to Wetback. System.

Cheers Hamish

Michael's brand new heater Ready to be collected and made to heat the water that mixes with the milk powder for his calfs. I recon these calfs will do well being warm over winter.

Thanks Michael.

That's right, there is no room in our garage for our cars because of you guys wanting heaters built all the time.

At least we don't add the lease of the building to the product. Heater packed ready to send, heaters built ready to be collected, and large heaters in construction phase to be sold.

This heater has now been SOLD.

One large garage heater left Sold, one orchard frost protection heater middle available, one fan forced heater right, sold. I tested it yesterday, it ran clean with and without the chimney. It is so clean burning it's incredible. Still requires the chimney for startup.

This fan forced heater has sold.

This fan forced heater is sold. We haven't used the wife's hair dryer, like half the guys on youtube, instead it's a heater fan which is made for this type of heating
Very clean burning, gives off a lot of heat for free well almost, apart for the small amount of power to run the fan. It has a small opening to remove the pan to empty every 12 months, cause there's nothing ever left to remove except the little piece of troweling you used to start it.

The newly built and tested Fan Forced waste oil heater, finished.

Comes with everything one length of 150 mm x 1200 mm Galv flue No cowling, oil feed, gloves and temperature gauge and if you pick it up, I will supply you with 80 litres of waste engine oil which will last about 40 hours burning.  

Excellent for a large shed, Garage or sitting in the corner of the workshop. The heat can be felt 3 metres away so that's a 6 metre diameter, and clean burning as you can see. Ideally run, between 350 and 500 Degrees F. 

The top 1/3 of the heater can be unbolted and removed to install a coil of copper piping for water heating should you wish to.

Thank you for contacting us. We will get back to you as soon as possible

Using Dried Corn for Heating the House
written by: Sidharth Thakur•edited by: Lindsay Evans•updated: 3/30/2011

Looking for greener, cleaner and more efficient fuels for heating up your house? Here’s an article that discusses how and why dried corn makes for a great fuel to use in heating stoves.

As conventional fuels become scarcer and costlier, homeowners are willing to experiment with and adopt unconventional fuels for heating their homes. Of late, corn has become a hot favorite for home heating purposes. But with that arises the big question – can you burn corn on the cob in wood stoves?

  • A straight forward answer to this question would be ‘No’, because regular wood stoves are meant primarily for burning wood, not even wood pellets. To use corn as a fuel for heating, a specially designed corn stove or a multi-fuel stove is what you’ll need to procure. Before we talk about how and why corn makes for a better heating fuel, we’d like to shun one of the common myths surrounding corn stoves. For most people who have never used corn as a fuel, a corn stove is meant for burning the cobs leftover after the kernels have been removed. However, that’s not the case and contrary to this popular misconception – corn kernels are burnt in corn stoves.

    There are reasons why the cobs are not a preferred fuel for use in heating stoves and the most important of these reasons is their low fuel efficiency and excessive production of smoke and dirt. Corncobs are mostly used for the production of charcoal, and although charcoal is a cleaner and efficient fuel, the cobs in their natural form can be very messy to use in heating stoves.

    Why Corn Makes for a Better Heating Fuel

    Even though burning corn seems to be a greener option because of the renewability factor, some people do have an initial inhibition about using this ‘animal feed’ as a heating fuel. Corn kernels are indeed a popular animal feed, but the corn kernels that are available for burning are the rejected kernels which are not fit for use as animal feed. That said - here are some more reasons to justify corn kernels as a better fuel heating your home.

    Completely Renewable

    Corn can be grown and harvested every year, thus its quick renewability earns it a higher score than even wood. Trees take many years to grow up and provide timber, also felling trees for fuel has a devastating effect on the environment. So when compared with wood, charcoal, coal or the non renewable resources, corn is the best fuel to use in heating stoves.

    Efficient and Economical

    Corn kernels produce more than four times the amount of heat that is produced by burning the same amount of wood in a regular wood stove. The heat efficiency of corn is comparable with that of wood pellets, and this high heat efficiency translates into great savings. The corn stoves come equipped with thermostatically controlled hoppers, which further adds-up to the economical efficiency.

    Cleaner and Environment Friendly

    As pointed earlier burning corn for heating is certainly more environment friendly than using wood, but its quick renewability isn’t the only factor that makes it a greener fuel. Corn kernels contain ethanol and oils, both of which burn efficiently without producing any dangerous gases. Also, the amount of smoke produced is negligible. Burning corn in corn stoves doesn’t leave behind any ashes, only a hardened clinker remains which is absolutely biodegradable and very easy to clean. Corn stoves are designed to pull in air from outside, which ensures that the air inside the house doesn’t lose its moisture and remains free of odor.

Email from Nigel.

Winter is coming though so I got back into it, made a frame for the water cylinder and plumbed it into the floor heating cylinder. Got it fired up today and the water is thermosiphing through the system, no need for a pump which is great. 
Still work to do, lag the pipes, make some heatshields,tidy it all up yahdeeyaydeeya.
And then see if it keeps us warm over winter.

Designed and built to heat homes or smaller pools                                                  like spa pools. A clean burning furnace.

Has a very large fire bowl. built to heat a 17,000 litre spa pool, complete with double wetbacks. 

This one is going to be all the techie gear on it, so a solenoid to cut oil supply off should the flame ever decide to go out. A Thermostat to keep it at a certain temp and not allowing it over that set temperature or under. Also fitting an automatic igniting system, so you'll beable to operate it without operating it so to speak..
The cost in doing this unfortunately not worth it, We light them and these go until you turn them off, simple and safe as that. 
It is available, but you won't have much change from your $1000 dollars plus the heater cost. 
Far too much I think.

The feedback from a customer, who purchased the plans, and built his own furnace.

last quite a long time.


Randy from Michigan USA, brought the plans only a few days ago, and now look what he has created from them.

Hi Randy, It looks hot. Thanks for sharing it with us.

Got to say you'll be needing it with all that snow on the ground.

 What do you think the savings in the heating bill, for your shop, and house, 

not forgetting he could make more that just one unit saving even more. 

This is his email reply, interesting.


My house and my pole barn (shop) are each about 120 square meters (1300 square feet). For this winter season, I paid about $2450 US for 1300 gallons (4921 liters) of propane to heat both. So to heat two buildings totaling about 240 square meters, I am at roughly $2500US for one winter. If I set up your design to use for heating the house at least during the time I am home (when I can keep watch on it), I could easily save a third of that.($833.00US) Not bad for free heat. We have about 500US gallons of engine waste oil at our business right now - that should 

So for the outlay of only $21.00USD for the plans and a little more for the building of the heater, he's going to be saving $833.00US a year that is a huge saving. If you look at the savings in NZD then it converts to $1124.54. 

The verdict, those plans at $21USD are far too cheap. lol.

I also sent Randy an email regarding the the oil feed line and how the smoke levels would change, once it is fitted to the heater. I also mentioned the great job he had done.

 His reply:


No need for me to take credit where credit is not due. It's your design, your testing, your hard work. All I did was follow a recipe and make a couple small changes just like any good cook will do.

I am getting ready to go 1200 miles away for a 6 week indoor project at a distribution facility so I am probably not going to have much time before I leave to do any further finalisation on this oil burner. The fact that it works and burns well is good enough for me. I have some ideas I want to try and by this time next year, I expect I will probably have made several with different modifications for different purposes (heating our pool, setting one up for a sauna, making one for my business partners garage). I am excited to install the drip line. It is ready and hanging in my shop but I am pressed for time so there it will sit for now.

As for the smoke, the video did show a little smoke but it was really a very small amount. I am confident that when I get the drip set up, I can reduce it even further but if not, the amount of smoke produced was what I would consider very minor for used engine oil.

Enjoy your summer. This morning it was -2F here and the high was +15F during the day. Kind of a "brisk" morning to be sure.



The New Orchard Heater.

The new prototype of orchard heater, designed to be placed between two trees to keep frost off the fruit tree.

Standing 200 mm off the ground to stop charring of the grass & ground. Burns fairly clean.

Runs on your waste tractor or car oil or even cooking oil which should be a huge saving. Has a slide air intake to clean up the burning.

The furnace comes with or without the cowling depending on your situation. 

Priced at $100.00 NZD without the cowling & $150.00 with the cowling.

As it is, waste oil is poured inside it and lite, with a gas torch.

If you are an orchardist and you like what you read about this heater and the savings, then send us an email, we'll be in touch.

Report from another customer that picked up his new hearter from Christchurch.


Just a quick note.  Finally picked up the heater the other day.  Was away with work which was a pain.

I am very impressed.  It is well made and thought out.  Instructions are great.  Its taken the guesswork out of everything.

Good luck going forward.

James, Nice brand New hot tub heater, on it's way to Christchurch. Check out that finish. 

These heaters are designed to thermosyphon, to give maximum hotwater output. 2 x 20mm wetbacks installed inside this unit. 

To the right, looking down inside the heater at the two wetbacks which exit out he second burning tube. These are right in the fire path.

Just testing to see how the new drilled tube works.
We have slipped the stainless steel mess tube over the drilled tube to hide the flame a bit.
We have only poured oil in at the start and not fitted the oil feed to the heater, but it seems to get going with the new tube and no smoke I really like it. The water would have heated up if we left it to run with oil feed, but just wanted to test the tube at this stage. another wetback is yet to be fitted.
It is a larger unit if you have a large area to heat, this would do it. 
Free heating water and air hard to beat. I apologize for the sound, it wasn't the heater making it I think it was the water. We have since sold this unit.
Finished & Sold
 Cleaned it all up and now in Matt Black complete with copper coil wetback, and thermometer.
This would be ideal if out camping and you need have hot water for showering and washing up, it is very clean burning and is now SOLD.
This is quite an amazing little heater, in what it can produce heat and hotwater.
Comes with the usual oil feed and 1 length of flue and cowling. Would be best setup outside.
I had this going today with the water connected to a 20 litre container, but only had approx 10 litres in it, within a few minutes it was producing steam and heated the container to the point where you couldn't touch the outside of it, in 4-5 minutes, it just pumped out steam not hot water and this was running heat wise at 220 F which it just over the 100 C. So this equals 11 Kilo Watts 
I took a video for you guys, but only went for a few seconds so wasn't worth putting it up. 
An amazing little heater, very clean burning too.
The large pool boiler. Priced at $2500.00 for any pool up to 70,000 litres, has 4.4 meters of 20 mm copper pipe wetback inside, complete with quality bass fittings.

The two wetbacks showing the hot outlet pipes.

This is certainly going to heat that 70,000 litre pool with ease.

Two more drip fed pool and spa heaters on there way to their new owners. 

   Thankyou to everyone who has purchased heaters and plans, this little invention/hobby has taking flight.

Constructed a metal bracket from the gas bottle handle and screw it to the wall. Perfect no leaks.

This is an inline water trap to remove water from oil.

How it works, is by using the long tube in the jar as the inlet, coming from your oil supply, waste oil enters the bottom of the jar. If any water is present in the oil, it will fall to the bottom, showing a separation between the water and the oil. The shorter tube is the outlet which feeds the burner which uses only the clean water free oil from the top. If the jar fills up with water it can now be removed by unscrewing the lid and emptying it.

How can you tell you have water in your oil?

It sounds like bacon cooking, it spits, sparks and pops like small explosions inside the burner pot. 

The water stops the heater from reaching it's correct operating temps so it has to be removed before burning.

The larger wetbacks now fitted into all hot pot 9 heater to enable pool heating up to 20,000 litres.

Two cold inlets at the bottom and two hot pipes outlets at the top, giving a 40mm diameter wetback.

When in full operation the bottom burner and the tube with the holes glow red, and those copper pipes are right in the heat zone.

I could put another length of pipe in it, it could heat your hotwater cylinder too.

I would think it could take 4-6 lengths of pipe inside for water heating.

But you really need to be within 5 metres of all the water units to heat.

Another one off to the Bay of Islands to heat their life and hotwater for free. 

Another large pool heater built, still the same size wetback inside it as the 45 KG ones, but smaller in looks.  The wetback is on the ground behind it which needs installing, and it will be off to Waverley to heat a 60,000 litre swimming pool and the pool outdoor area all for free.  

All welds checked and buffed.

 All the old paint has been buffed off, and  re-painted with heatproof paint.

Very tidy. The two wetbacks fitted and another one will be on it's way to it's buyer. Free pool heating at it's best. An amazing product.

This sieve was cleaned before I poured in 40 litres of waste oil, look at the crap it collected. A very cheap basic filtering system that works amazingly well, and this is our only filtering we do before the oil is burnt, apart from removing the water from the oil.

Make sure you filter your oil before you burn it as this stuff will block most taps and needle valves up all day long.


Nigel's new drip fed waste oil heater finished, complete with smoke catcher and with 20mm ladder wetback, ready to forward to the freight company today. Designed for long term burning with the large burning bowl. 
This heater is designed for spa pools and hot tubs with its ladder wetback installed.

This radiator is putting out 61,354 BTU/hour or 17,981 watt.
So yes the radiator is heating the cat not the other way around.

-3 degrees tonight, and look who's found the warmest place in the lounge 44 degrees underneath him.  Was a rescued cat, been living wild, now three feeds a day, has his own personal guard dog to break up any cat fights that may happen between him and his pedigree burman brother from another mother.
He just loves the radiator, he's sound asleep on it now.
The radiator is heated  from the drip fed waste oil heater outside. No pumps or power used with these heaters. The hotwater risers up from the heater, heats the radiator and as it hits the cat it cools the cold water then drops down to the heater outside to be reheated and sent around again and again all day long heating our home and the cat.

Aaron's new drip fed waste oil heater for his bus is on it's way to Wellington. That Bus is going to be so warm inside. 

Excellent for inside protection over the second burning tub stopping any smoke that might want to go elsewhere but up.
A nice heater  for a bus. 

Ken's huge drip fed waste oil heater finished and sent.

This is now heating his pool, a very big unit. For serious heating requirements. Pool size 80,000 litres.

Has a ladder wetback below image inside it.

Currently installed at Waverley.



The wetback going into this 45 KG pool heater above, now to be welded up and about to be installed. Pressure testing and any holes welded up again.

It's over a metre in length total and 220mm wide x 20mm copper pipe.  

Built to heat a large swimming pool.

A few heaters wrapped and ready to be delivered. 

Order yours now.

We send these palletise now, reducing any damage in transit. 

The other old faithful in my life, she's so Hot she's had a new lease of life after doing a 2 year stint without any maintenance on her at all. 
She's just keeps on giving us free energy year after year. This year we are replacing the galv flue with stainless reducing rust flakes falling inside it and building up. The flue is about 5 years old so time to upgrade and update it.

The galv flue has been rusting over that time form inside, sending flakes down inside the burning chamber, and  sitting onto any ledges it could find on the way down, stopping it even from lighting up properly. Time for a clean.

So I pulled it out cleaned inside and out, shouted new legs and larger pot, new pot housing, cut the tube off , and cleaned inside re-welded it back on. Made a heat proof cocoon from a 44 gallon drum, and re plumbed the wetback, don't know about the blue, we may have to paint that. Fulled the radiator with 6 litres water, then light it up. It's heating at 250 Fahrenheit and the radiator is running at 44C degrees. The oil is running just slightly more that a drip, pouring into the burner. I do like the larger pot rather than the thin frypans. I find ash doesn't become a problem anymore.
The other thing,  I can't hear it going from inside the home. Brilliant  really pleased with it.  Just need to level it up when she cools down. Oh No smoke excellent. I don't think there would be a cheaper heater/furnace on the market, not only to purchase price but the running costs. 
Get yours today and start saving yourself, one hell of a lot of money.

A few images of the heater operating at 950 degrees Fahrenheit glowing.

Right Here


Here at Drip Fed Waste Oil Heating, we design and construct all types of waste oil heaters for your heating requirements, large and small, for home heating, hot tubs, spa, and radiators even swimming pools.

We can setup a system for your own home, giving you a firm quote,  wether direct heating from the unit or via hot water through radiators.  

Please get in contact should you want more information about this.

Being a free form of heating, the demand is steady, not only for the warmth but their water heating ability. 

Able to be installed outside the home seems to be a great advantage. 

Running on a waste product which normally cost the garage and fish n chip shop money to remove, is available all year around and totally free from alot of these outlets, any tidies up their business too. 

Burning up to 1- 1.2 litres of waste oil an hour you don't need a huge amount to get through the week. One 20 litre container lasts four nights burning with the help of a needle valve now.

Burning cleaner than a wood fire, and the cheaper price, makes them a great option for the outside sheds & workshops,garages, hot tubs and spar pools. 

In New Zealand, we are now coming into spring, and we have had a few very cold winter days and nights, and we will have more for sure, but it is certainly warming up which is nice. Maybe you need to start thinking about this type of heating for next year as the cost of firewood is not a cheap option, I saw a tandem trailer load of gum last week on the side of the road selling for $300.00 how many trailer loads will you burn over winter 3-4-5, these waste oil heaters sell at $550 for just the heating and $650 with water heating capability and 99 percent cleaner burning than the wood fire.


The waste oil heater has been connected to a 1800 mm water radiator inside the lounge. The water thermosyphons up to the radiator then, as it travels along the radiator, it cools and drops back down to the heater to be recycled and reheated again and again all day long. the radiator holds 6 litres of water, we have used 20 mm copper pipe for the piping, which is insulated.

The waste oil heater runs outside at 250-350 degrees F ,and is enough to heat the whole house upstairs after and hour.

It a lovely form of heating, the radiator heats cleanly and within the hour the place is warm but not stinking hot.


Well known for the use of hot houses, there's a lot of interest in these "drip fed waste oil  heaters" and their free heating capability. So long as everything is kept clean from oil and you don't need to touch the stuff it is a great source of free energy. 

Piping it to where the fire is, is a good idea, using taps and drums to contain it. Under the fire we require you to have a catchment area should oil drip at any stage, and it is a councils requirement that storage containers of waste oil do have a catchment area too. 

While we are on safety issues the heater will need cleaning out the every-time you start it and every 10 hours of burning approx this is to stop the ash building up in the frypan.This is only frypans as they don't hold a lot.

We now build them with larger pots. The cleaning of the pan can be done with a screwdriver to flick the ash into a bag to contain it, and keeping everything clean. If you have a pot installed this will last many hours longer. Soot and ash can accumulate up the second burning tube, so it would pay to stick a long screwdriver up inside it from time to time and clean it out. 

The flue will require the odd clean too. It will burn alot cleaner cleaned out regularly.

 I trust my heater to operated a the same temperature, it will not alter. I turn on at 4pm and off 10.30 ish I will check it when starting up other than that.  When I'm finished with it I turn off at the tap, at night and go to bed without checking it is out, it is that reliable and safe.

Selling the complete units are a bit of a hit with my customers. There has been no complaints to date, which is excellent. Mind due, who wouldn't be happy with free heating. Time for change maybe. So long as you have the ideal area for it of course. If waste oil isn't your thing, use canola oil, from your local fish n chip shops, you'll need to filter out the wildlife, chips, sausages and bread crumbs before burning.

I have a few guys building these waste oil heaters, off the plans at the moment, which I'm in contact with weekly, just to see how they are going and checking that they are having success with their build. Check out the customers waste oil heater builds Tab.  

It takes me about 6 trips or so during summer, collecting enough waste oil in 20 litre plastic bottles normally 80 litres at a time to heat the home through all of winter. That's only as I full the car up with petrol. I don't go out of my way to collect it either, and never will pay for it. England has had these types of heaters everywhere doing their bit to remove this oil cleanly from our planet, and it has been around for years so it's not new in anyway, just recycled.

The days of cutting live trees down for firewood and, splitting them up into pieces and storing them under the trees over summer to dry, then moving it to the wood shed then into the fire box then into the fire to burn is finally over. It use to be a major undertaking I know. Now its pull the pan out a bit add 1/2 cup of oil/petrol mix and maybe a piece of rag, light it, and turn the oil flow to where it needs to be and walk away, turn it off at 10.30pm. It's that easy. 

The type of oil that can be used in this heater is engine oil, from cars, or trucks, transmission fluid, diesel, fish & chip shop old waste canola oil. 
Basically it needs to be engine oil without contaminates any oil will work in this heater, and the best of all is all of the above is available locally in large quantities. 

It's the kind of heater, I trust, I can leave it for hours, go into town come back and it's sill the same temperture as when you left. It doesn't alter, once you have it set. I use a brass needle valve/air line taps for the oil feed. Needle valves makes waste oil burning safer. So if you are making one just from the website please invest in a needle valve, they are not cheap, but well worth it. It has to be totally safe. A catchment area under your fire for any spills/cleaning that may or may not happen. Be vigilant about the place you install it.

 Even though its safe you still need to be careful.  

If you are thinking of heating your home with it, I would suggest that the heater be placed outside the home, and screwed on a concrete pad with a red brick firewall surround and a roof of sorts, and running hotwater pipes inside to radiators inside the home.

If you are thinking of heating that cold shed/garage then install it inside the shed for its radiant heating ability away from anything combustible of course maybe even a corrugated fire proofing around the back of it. 

Waste to Wealth.

Did you know 80% of the worlds waste oil is burnt for heating.

We've done the hard yards for you, we sell waste oil heater plans & complete heaters units, with and without wetbacks, that are proven to work with very little smoke, and they can heat your home totally free.

These heaters as they will give years of free heating.

Cleaning the inside out every two years isn't to much of a mission.

Remove the flue and suck out anything that may have come down the chimney and sat inside the edge of the bottle. 

Check the holes are open, clean down and repaint it good for another couple of years.

My thoughts are, do it right from the start.

The hot pot 9 will do everything you ever wanted in a waste oil heater.

From heating your water, and the air around you.

The plans come complete with images on how to build it and explains exactly how to build it properly and where to source the products.

A lot of these bits that we use most people would have around their home rusting.

A gas bottle some flue your half way there.

The last guy said to me it cost him $10.00 for the 150mm tube and 38.00 dollars for the copper oil feed and tap, all the rest of the stuff he had laying around his home.

And when I went to see it, he had it all painted up and going.

I will help you throughout the build so you get it right the first time.

An email from our customers: 

Thanks for this Hamish, -   Brad here from Melbourne Australia

Hopefully I get make one of these,  I'm a bit tied up with a few things at
the moment though,  (... and I can be a bit of a " gunna " lol )

I decided to buy your plans purely because it appears to me that you've done your homework, and that its a tried and proven design.
and I'm sure you wouldn't be selling if they weren't,....

I particularly like the fact that that there is very minimal smoke etc. that is a must these days..

I have one question please, I was hoping to make a slightly more compact
version, not so high overall about 300mm - 400mm shorter in height

Is this possible by shortening the legs slightly, and also the burn tube etc.  without effecting its efficciency much....? 

Thanks Drip Fed.



The plans look really good and i can see you have put some considerable thought into them.
Thanks again for the plans.

Yes, 99% smoke free. Runs cleaner than my home log burner definitely. I added another 1.5m of flu I found at the dump and that made all the difference. Draws better, burns cleaner. Only smokes on start up really and if I get  a bit of water in my oil. Only issues I'm having are with my fuel feed line getting blocked now and again so I'm going to start filtering my sump oil somehow, probably just a mesh strainer. 
To run this hot tub in winter on electricity would be $70-$100 a week! No chance. I got the tub for free from a bloke who couldn't afford to run it anymore. I'm really thinking about if I extend my house one day I'll get another one for a house radiator, it's so good.


I've welded all the holes in the tube now look going it almost is impossible to do have a fire with nothing coming out the chimney. The only problem with is it doesn't get up to 400 degrees F so holes where put back into it and is still smoke free and heats my house.


Radiators provide radiant heating. That means a solid object (in this case, the radiator fins) is heated instead of the air itself – creating gentle, ambient warmth that evenly heats the room.

Central heating radiator design has come a long way since the institutional school heaters of old; today’s models come in a range of styles and sizes to suit all kinds of interiors. They can be linked to a variety of boiler or waste oil heater, heating systems and are free to run, when linked to an energy-efficient water heater, like a hot water waste oil heater.

Radiator heating is an excellent option for existing homes because they can be easily retrofitted to your existing heating system.

Even Pussy Cats around the world are logging on to this website to finding out more about this free heating system from
Drip Fed.

I want to show you how easy it is to heat your home totally free this winter, and without smoke or loads of firewood or power or gas. It's a clean burning waste oil heater, you don't believe me, then watch this video.

I say free heating but there is an initial cost of setting it up. 

An estimate in having this setup in your home with radiators is approximately $2250.00 and that's all never to spend a dollar more for you're heating. The oil you would need to collect. Which could be done from your local fish n chip shop or local garage of if you are local I could even share my supply of oil as there is just so much of it.

Radiator Heat settings

Oil Boiler Temp        Radiator Temp

350 Fahrenheit      42 Celsius                    

This is the temperature I get from the waste oil heater running at 350 Fahrenheit and the corresponding temps the radiator inside the lounge is pumping out 43 Celsius. 

The fire/Heater was removed today, and 20 mm holes drilled, for copper pipe to be inserted through the 150 mm tube and into the garage, and then up to the radiator. It will thermosyphon by itself so no pump will be required or pressure release valves either.

 I used Crox fitting and hemp and graphite for the whole job.

The Radiator is now plumbed in and was tested to see if it could make steam, on  low fire heat setting, and Steam it made.


I used 20 mm copper piping there is only 2 x 150 mm of it through 150 mm tube with the holes in it. I had the plumbing guy in, with the delivery of copper pipe and he was amazed at how I made steam from the waste oil boiler totally free. 

The copper pipe and fitting were expensive. Got it all going and it now it heats the whole house totally FREE. See the video to the left. As it's not conected to the main a pressure release valve wasn't required.

 I ran it for 6 hours, the whole house got that hot, I had to open windows and doors to cool down, roll on winter I'm ready for you.

 I was amazed the cats weren't lying on each end fast asleep. It'll Happen!! 


The wetback system constructed with 20 mm copper Pipe and crox fittings and that's enough to heat our house amazing eh. The waste oil heater working hard in all weather, This is one of the oldest waste oil heaters we have made and it has provided us with lots of free heat and been invaluable this year again. A rusty  oldie but a goodie.

It has been outside in all the elements now we have a padio heater cover over it to stop water entering and slowing down the rusting.

I have just pulled it out yesterday and have given her a clean inside and out, Complete with a paint job she's going to go another two years before we do this again. 

Same picture as above but running at 450 degrees F at night, heating the water.


With my heater, has now been operating for the last two years without a clean, now I see soot flakes have started to expel out the flue at start up.

The other night the fire snuffed itself out, it got that bad. S

this morning I cleaned the flue and the burner inside, what came out, blocks of carbon build up and flakes enough to full a bucket, after seeing that, I dought if any nasties get into the air, as it's all kept inside the heater.

So maybe a clean once a year maybe good advice to you guys who have purchased these heaters, and who have built there own.

That's about the recommended time for a wood fire, so as we are looking at "clean burning" it's a good idea.     

I burns very clean now.

This was our waste oil heater for the past two years.

It has been brilliant, all the free heat you would ever want, at times too much heat, just far too powerful for inside our home so it's been sold for pool heating.

 I remember my daughter with her back door wide open in winter, freezing cold, saying "it just too hot dad", Not that it mattered wasting all that heat it was free anyway. 

I started my hot pot 9 heater, popped in the starter fluid, lit it, turned on the oil flow, and within a few minutes realise it was sounding like water was in the oil. The oil had built up ontop of the water, not too much, but enough to startup my own Chernobyl reactor with that sounded of bacon cooking with the odd explosion inside the pot.

The temperature whipped up, and the smoke became dark out from the flue, like you were burning tyres, and stand back, I turned the feed off. The wife sticks her head out the window it sounds like a truck coming down the street, You OK she said. I thought, she would be use to that by now, with all the experimenting stages, had a few of these, but with this big oil heater. It started blowing smoke rings out the holes in the tube, very impressive. So don't let the oil build up at all or look out. 

It soon came right and settled down with not a drop of oil floating in the pan just glowing ash. So this is how these should burn. 

I must say that the water trap works so well, I haven't ever had that problem again. 

I have tried the hot pot 9 burners with the bigger pots, and have tested them to see if this would happen, and I wasn't able to get the chernobyl reactor going in these, it just smoked a little bit, but didn't go into that burn off stage which is great. This is when you need a catchment area incase you supply more oil into the fire than it can burn and start overflowing from the pot. Cause waste oil is a awful stuff to clean up.

 Statistics are averages taken from various online websites.

The Hastings District Council doesn't allow waste engine oil being burned in anyway, yet in some cases it allows  Kroll heaters, and there are quite a few business using these waste oil systems, sound like the some pigs are better than other pigs syndrome, however I would say Canola oil from you local Kools Chicken Dairy is only 200,000 btus under waste oil. Still good for heating but will need filtering to get the chips & crumbs and wild life out of it.

My wife was about to pour a litre of used canola oil down the drain, how many people have done that before, I stopped her and said don't waste it I'll take it and heat the home with it for an hour. 

Check out for more of the begining videos. thiis was the testing the smoke stage. The finished video same as above.

Ash build up

The results of burning waste oil for 6 hours at high temperatures. If you burn't for twelve hours, there wouldn't be to much difference in the amount of ash.  I used a small piece of towelling to start it, however I don't think this is required at all, as most of what's left is the towel. To remove it turn the pan upside down, most of it will fall off. 

When it is burning correctly all you see is flame, no oil floating at all in a pan.

At 550 - 650 degrees fahrenheit we would be looking at up to 1.8 litres per hour.

But really does this really matter, as the oil is free.

Since I have put a larger bowl and cleaned the old girl up, we seem to be running in economy mode @ 350-450 and the radiator s running at 

42 degrees C and that's plenty to heat the whole house.

Thankyou to all that frequent this website.

I can now work in my garage when its cold outside. And i don't have to throw my oil away so i love this kind of heat! Thanks Doug.

The old faithful 2 years of keeping our home warm.

It's just too big and too much heat for our home so it is now off to Whangamata to heat a spar pool. 
Make sure the bubbles are from the blower not the heater. I do hope you enjoy all that free heat it puts out.
Thanks Doug.

If solar hotwater is the thing your interested in, then we have also fitted a solar system on the roof, and if you want some information from someone that isn't out to sell it to you one expensive unit, then check our solar website out. Pro's and cons on it. It shows how to build your own retro fitting to fit your existing hotwater cylinder and how solar controllers operate.

Like all solar units, when the sun don't shine buy a waste oil heater.


The Team at Drip fed waste oil has constructed another waste oil heater for you to view, soon after construction in testing mode. It reached 550 degrees F for one hour and ran at normal temp of 300 degrees F, turned it off after 9 hours. It went through approximately 8 litres of waste oil in that time. It a very safe and reliable heater, stays at the set temp and didn't alter at all. I did leave it for an hour while I went into town. The units smoke level is very little, and I think is acceptable and will improve with more than 1 length of flue on it and time.  

An excellent heater, available to purchase through this website, and at the moment through 

The plans for this heater is now available through the Purchase your heater and Plans tab at the top of this page.

Please notice in the video above, that there is not a drop of waste oil anywhere on the ground. We do like to keep everything oil free. And there is No smoke at all when in operation. This heater has been up at 650 degrees F, it would go even higher however the temperature gauge doesn't.
This heater is clean burning and never smells of oil.

I have temporary install this heater in the garage, and been running it today to check for any smoke leaks, all good.

I have since installed it outside the home. 


To My Overseas Customers Thankyou so much for checking us out.

I see a lot of people from around the world looking at this website, and I can see why, winter is approaching somewhere in the world, heating becomes a major money concern.

Firewood is a huge price nowadays to keep the family home warm and can be a lot of hard work in getting the stuff. 

A twenty litre plastic container of waste oil will heat my home for two nights. 

I have priced, to send a waste oil heaters over to USA, the freight price is for one unit is $800.00 NZ, just not worth it. So get out in that shed of yours today, and start making one for yourself. Stick some copper pipe in it and your've got free hotwater too. Purchase the plans first so you get it right from the start.

I'm prepared to help you make your own, and help throughout the build.

All that is required to build this heater, is a welder, an angle grinder and a drill and steel

It is all set out in the plans, each step with images to show you what yours should look like. I have had people copy it from the picture then ask me a couple of weeks later, why theirs smokes like a --------- and mine doesn't, well there are a few secrets.

Buy it once and get it right from the start. Don't try coping it from the images and ending in a smoking out your neighbourhood on a still day. It happened to me a couple of times a few years ago now when, I began building these, how embarrassing, It's not funny when this happens at all. Thank god those days are over for good.

All the best, and I will see you on the other side.

Regards Hamish also known as Fireman Jim on YouTube.
