Welcome to Drip Fed Waste Oil Heating.com
The h

The 45 kg waste oil heaters we sell. In the video above has been running for over 14 hours today on waste filtered engine oil, I've done nothing to it in those 14 hours, haven't even checked it. It also ran for 15 hours, total the day before without checking it, turned it off by via phone late that night. 

We have found these heaters easy for customers to operate with the waste oil controllers.

We are all about safe, clean burning, of waste, used engine oil, canola or veggie oil.

We also offer our plumbing experience when plumbing up these heaters to water.

Heater Prices;

Prices for a basic 45kg heater. $1199.00 This will heat up to and large workshop to even larger areas.

We have these basic 45kg heaters instock.

Heaters with a copper coil fitted.

$1490.00 with a 15 metre coil fitted. This heats spa pools, small swimming pools to 10,000 litres, hot water cylinders, radiators. 

$1790.00 with a 30 metre copper coil fitted. This heats larger pools 25,000 litres, multiple rdiators, underfloor heating.  

Maximum coils are 3 x 15 metres sets @$299.00 per 15 metres coils. Each coil is 12.7mm diametre. This will heat up to 85,000 litre swimming pools or a smaller pool  with spa pool, with two coils and hot water cylinder with the 3rd coil.

A three coil heater selles at $2200.00 because the extra fittings needed to connect to a 42mm copper pipe manifold. 

The latest waste oil heater been built. 

The changes we've made to previous units, is the blower unit, now square pipe, rather than the round pipe, this speeds up production. 

Cylinders are now cleaned down before we start, back to bright steel this gives a better paint finish.

Image to the right shows the packaging setup with everything packed inside the cylinder apart for the blower unit which is on the side.

Paint is heatproof to 650c

Although the paint is heatproof it doesn't seem to stay there for very long, the heaters with coils won't ever get to 650c so I don't see why this can be. I tend to keep the paint up to it as ours sits outside in all weather. And it is used to demonstrate waste oil heating. 

Most welcome to view it going anytime just fill a form out well get intouch. 

We have just built this copper coil to heat an outside bathtub, or the coils could be double to heat a spa pool. We have it for sale at $179.00 NZD.

$239.00 for the spa version.

It's 280mm Diametre and the extensions are 400mm long 12.7mm tubing x 3.5 metres.

Can light firewood fire under or around the coil or both to heat the water, or a gas ring with a rubbish bin lid ontop of the coil to keep the heat in.

email us if you are interested. dripfedwasteoilheating@gmail.com

Just making this coil up for an outdoor bath 415mm od coil to fit inside a 44 gallon drum. 15 metres x 12.7mm.

Just got to pressure test it and fit ends.

It's upside side down currently. The drums on feet, the top exits the bottom of the drum for the cold inlet. A woodfire happens inside the coil and then you get boiling water.

We have put this on the shelf until we have the time to get back to testing it again, I think a diesel and petrol mix might be in order as a starting fluid rather than trying to start it with just waste oil.

Something a little different, a flame thrower.

Yet to throw a fit, let alone a flame.lol

At the rate I've seen these heat water we think it would heat the 88 litres of boiling water in 36 minutes or less.

But have yet to see it going correctly.

Why we think you should turn to our blower burner units rather than a waste oil or diesel blower burner unit is;

Our units burn waste oil without the need to heat the oil to 85c.

Our units use a fan not compressors for airflow, and I understand these burn out a lot of compressors too.

Therefore ours are quite when operating and runs off 12 volts adaptor or car battery.

Some of the waste oil blowers burn around a gallon per hour of oil, we burn up to 1.2 - 1.8 litres an hour.

They come with huge power accounts to pay at the end of the month, ours almost nil.

We build them to suit your needs not one fits all. 

Ours are made in New Zealnd, Australia, America.

Theirs are often made in China.


This customer contacted us, to see if we could build a waste oil burner blower heater unit for her Marshall boiler, she had limited space, a Diesel burner like the one above was heating the boiler, however it also ran off wood, a log fell out of the boiler and burnt all the electrics on the diesel heater, hence the burn mark up the wall. It was going to cost thousands of dollars to replace the diesel blower unit, then she found this website.

So now she has our waste oil heater fitted with a controller on the wall and has no more costs for her hot water.

Doesn't need diesel anymore nor firewood. Just free waste oil, which we all know we can't burn it fast enough as the supply of oil keeps on coming.

As these burn for long hours a Ryco oil filter/water trap, has been fitted to reduce the ash buildup in the pot.

The waste oil comes from outside the house, stored in an old central heating storage tank and is pumped in via the controller unit.

Total cost for blower burner and controller $498.00 Plus $99.00 for the filter. Total $597.00

Price of a diesel heater anywhere from $3,000.00 plus fuel and power to run it, and a few compressors with lots of noise. We have since found out that some people with these diesel burners are not only burning diesel but burning out compressors too. 

Best to date 5 compressors.

It starts to look a very viable cheap option.

Instructions on how to fit the unit to your heater, and how to operate it.
With free online or phone help for any issues you may have for as long as you require. 

We're built a new type of used oil heater, it operates like a cyclone effect inside a cylinder, and the flame rotates it looks like a yellow donut and look really cool. Controlled with our waste oil controller.

With any oil fired heater, if you put too much oil in any waste oil heater they will eventually smoke, this heater is no different.  

Was a bit of a mission to build as the steel was very thick.

The video of it is below. We would make the next one, from a 45 kg cylinder next time there something about the dimensions that work with them.

 I'm hoping to heat the oil prior to being burnt to get that lovely blue flame. That didn't work.I found out the guy who was getting a lovely blue flame was burning waste oil, diesel and acetate which isn't free. Defeats the purpose when oil is free. 

We have since had another tree fall into our place form the neighbour, it's been dead for 13-15 years they never did a thing with it. I wrote a note a week ago to them regarding cleaning the mess up, six weeks on I see the note still sitting in the white plastic bag on the lawn. Neighbour from hell, never mantains anything, lawns 3 feet high.  So got the chainsaw out and cut it up and it's heating the house with this heater with wood just to get rid of it., still free heating. lol

So the conclusion on this heater is it smokes has been removed and is excellent for firewood I've removed the coil. Looks good but not good.

I will eventually change it to have a blower burner unit fitted to it when we get a bit of free time.

Today the new / old heater is being replaced with the new 45kg heater, we are looking into the water temperature this one coil or 15 metre heater puts out today, so water temp will be measured and the output will be measured also the flow rate, to give everyone more idea what these heaters do. 
We connected to the garden hose to the heater, the water entering the heater was 14c, water was flowing at 10 litres every 4 minutes.
Water exiting the heater was 75c  Burnt very clean, was enjoying the warmth it was putting out. 
Now this customer Ross will have 30 metres of copper fitted, he'll get twice the flow rate 20 litres every 8 minutes @ 75c.
This will be connected up to our radiator tomorrow. In a closed loop that water will be entering the heater at 35 c and heating the radiator around 85 c. It takes a huge amount of energy to raise the temperature of water by 1 degree, We raised it 61 degrees all totally free.
We are giving away a huge free source of energy recycling it. 180,000 litres of waste oil a year 80 percent is burnt. Hopefully cleanly.
I installed the new 45 kg heater with one copper coil 15 metres inside the radiator,  connected the coil to 20mm copper.
I sent this video to a mate.
It's going really well, I'm over the moon with it, Brillant, it's running the radiator which is 2.5 metres long double skin at 85 c. The waste oil controller is running the heater at 6 second delay and 1 second pump. I ran it at 2 second delay it just exits a huge cloud of steam out the open vent filling the loop with cooler water. The flame was roaring in the pot which is how it meant to operate. Oh yeah the main thing, it's very clean burning without any smoke, finally.
If you want one of these send use your requirements.
Now is the main heating for the home once again. Just works as it's supposed to. Nice free clean energy.
                                      The new fans have arrived pumping out 140 cfpm amazing sounds like a small jet engine.

Auto lighting from your smartphone.

Results so far have been looking online at Electronic Flame Ignition and I think manual ignition might be the way to go, as I doubt whether you want to pay $1000 us dollars just for the igniter plus freight from the States.

We haven't exhausted it as yet we still have Combustion Controls to talk to. However these units are used for commercial dryer heaters or jet units dryers so these won't be much cheaper either, so back to my setup which I'm expecting more parts arriving any day now. I have since found these have been lost in the post, just not ment to happen eh.

So will continue to work it out.

Ok I've started it. Yah. 

The auto lighting would come in handy for commercial operations for heating water, like dairy farming, Campsites, etc.

I've wired up the thermostat to 12 volts and a timer so when the water temperature reaches a set temperature let's say 75c or whatever temp you need it set to, the thermostat will turn the timer off. When the temperature drops belows say a set temp of 60c the thermostat will turn on the turns timer on to and opens up a solenoid connected to a 9kg gas bottle which will allow gas to flow for only 10 seconds then stops, and as the gas starts, the auto lighter turns on at the same time igniting the gas flowing into the pot in the heater. The pump and timer would start simultaneously. 

Next step is connect the solenoid up to a gas cylinder, We have the gas connections for this.

The wifi gear is here for it.

The power reducing controls have arrived and I have wired that up, and now the zappers have arrived so it's just a matter of having the right frame of mind to attach it. It's on my bench.

But now I have to connect the waste oil controller unit to this auto lighter unit with a push in plug, so the timer will turn the oil/pump on and off when the thermostat turns on and off. 

And been thinking maybe the fan could stay on because if the heater is 60c it still needs air to stop the heat coming back up the blower pipe melting the fan or speed controller. So the fan will be kept on very little power consumption.

It's going to take a while, as each operation needs to be figured out, and wired up accordingly. 

Since fitting this Ryco oil filter to the oil line, I have notice when i went to remove the pot to clean it (normally there's alot of white ash to get rid of) there was alittle black smudge on the steel, inside the pot with nothing to remove, and that's after 7 hours of use. Normally there's about 1 1/2 cups of ash. I wonder if filtering it to 18 mircon has changed it in some way. If anyone else has found this let us know.

You can see how hot that bowl inside the firebox is, white hot, I can say the emissions will have nothing just a clear heatwave. Perfect.

This is the cheapest way to get into waste oil heating just by adapting what you have.

Sending heavy 45 kg or even 19 kg steel cylinders around the world is too expensive.

Everyone has access to these types of log fires, and alot of them will still be good, certainly fine to have outside, and most of these have wetbacks already fitted, so heating the swimming pool or the spa pool just got alot easier and cheaper. 

                                                                                               Great to warm up the entertaining area. Excellent for heating Radiators.


So all that's required from us would be the blower burner unit, and the waste oil controller, to heat.

Ideally we would need to know the total measurement, height and width of the logfire to build a blower burner accordingly. 

                All you have to do with the blower burner unit is cut a 2" hole in the top or the side, back of the firebox and 4 bolt holes. 

The hole could be square or round either way is good, as the bolt on steel plate will cover any gap.  

No more firewood and free heating and if you have a wetback your power account will also drop by half.

Add up the firewood savings alone in a year, and all that extra work involving firewood.

Sell the chainsaw and tralier and towbar.

Waste oil is similar to burning propane we have found. Turn it on, let it run day and all night turn it off.

Empty out the ashes in the pot every 20 or so hours depending on the oil your burning.

Another waste oil blower burner converted logfire.

Well done you guys.

We built the blower burner unit and waste oil controller for this unit.

The oil is in the plastic 20 litre container on the chair, waste oil controller sitting on the chair, blower unit out of sight entering the left hand side of the firebox.

The oil container can sit on the ground and the controller could be screwed to the fence for easy access.

Notice all that heat and no messy firewood, and that's a big firebox.

We also understand this is heating a spa pool at an amazing rate too. I think the rate was every second 1 litre of pool water was heated to 70c, so 60 litres a minute 3600 litres an hour the spa pool should be boiling and ready to cook the first batch of crayfish in two hours. I suppose you could turn the fire down if a slower heating rate was needed.

To take this system to the next level as a few have already, to heat 8 radiators, showers, spa pool, etc, take any logfire with a wetback, it would need to be connected to a 280 litre new or second hand hot water cylinder, the logfire would heat the water to 90c in the cylinder, then at that temp, a thermostat would turn on, the circulating pump, pumping the heated water from the cylinder around the loop to the rads. I would think four rads in each circuit.The only thing is rad water can become dirty with a little rust so you may need a filter to remove this if heating a spa. Or have seperate loops stopping the water from mixing somehow.

This is the only heater we build now, because these just work, they are clean burning and can be used from drying firewood, heat aircraft hangers, homes, radiators, spa pools, swimming pools, sheds large workshops, there's no limits to what they can be used for and the customer can get their head around operating them which is a must.

                                  Now this smudge pot is running on diesel, could you amazing 40 of these per hectare. OMG Please No.

                                  Now these are currently allowed to be used today on orchards for frost protection they should be outlawed. 

                                  Remembering these get lite at night so this smoke we never see but that doesn't say this isn't happening, it is. 

                   These things need redesigning to burn cleanly not like they are currently if they are going to be allowed to be used by Councils. 

                                                           Issues with burning waste oil.

              The above picture  councils in the past  have turned a blind eye to this on farms and industry for years and now it's becoming an issue.  

                            It's not just the oil that needs cleaning up but the ground needs digging up and removed. To where we don't know.

I know our heaters are cleaning this carry on up, we have customers that tell us they have 100 x 44 gallon drums full of oil out the back of the sheds.

We have an issues regarding controls in place regarding burning waste oil for heat recovery, even when burning it cleanly, and who is, and who isn't, allowed to burn it, and the way in which they are allowed to burn it. If your in a residential area you are not allowed to burn waste oil unless you look into used oil, but if you have an orchard over the fence from you,  all good mate, they are allowed to burn it for "frost protection", and can be burn it anyway they see fit, even in an open 44 gallon drum (not a good look) or their dirty smelly smudge pots, so this makes you think, the issue isn't the emissions or the dangerous chemicals released into the atmosphere at all, or even the awful smell. Now we aren't talking 1 smudge pot we are talking up around 44 smudge pots to the hectare that's alot of smoke and you only really see this smoke in the morning as they have been burning this crap all night in the dark. So why are we not allowed to burn it when the emissions are cleaner than their "approved wood fires", and only 25% emissions of a family car, it really does make you question this issue. With more and more oil to be stocked up in rusting 44 gallon containers, I know for a fact people will just pour it back into the hole in the ground or drains, water ways to get rid of it.

We are far better burning this stuff to remove it before it starts damaging the planet, stopping it from entering our waterways, rivers, and sea from becoming another oil slick.

Yes I agree totally we still need to have these heaters checked and emission reading taken regularly so as to keep them inline with the Councils clean air policies.But no counselor has mentioned anything.  

Ok, you say this is adding to global warming, my augment is this type of heating doesn't involve cutting down oxygen producing trees to heat our homes. etc  we are leaving them to grow to remove the Co2 from the air.  

I get annoyed when are brainwashed by Councils that these chemicals entering the atmosphere is highly poisonous when we know that's not so. 

It's  even too difficult for these councils to separate out from from "waste oil" veggie oil and canola oil as a ok oil to use in a oil heaters as it's outside of the HSNO act. They aren't at all interested to improve any idea or even look into it. I really wonder why they even do the job if the have no interest at all.

I see WorkSafe has these type of heaters on the lists as a approved heater gasifying waste oil on a hot piece of steel.

Soon you won't be allowed wood fires because they give off Co2. My mig welder might be next as that goes through the Co2. Watch out your soda machine may be next. Co2 is everywhere wake up.

I think they need to look at banning diesel trucks on our roads that don't have Add Blue to neutralize their emissions.

And cutting down trees for firewood should be stopped not that i'm a tree hugger. 

                                                            All of these heaters need to be bolted together by you the customer.

                                                                    They are also recommended for outside use only.

We just found this write up regarding waste oil heating.

Burning waste oil to solve a burgeoning environmental problem sounds like an alarming contradiction in terms.

However, with a growing plague of waste-oil stockpiles around the country, more and more businesses are using waste-oil heaters to heat water, and there are applications for households, as well.

Sales at two-year-old Cromwell-based burner supplier Omniheat New Zealand had more than doubled in the past year, distribution manager Dion Prentice said when contacted.

"Basically, it's turning a cost to business [oil disposal] into free energy for them,'' he said.

Waste-oil water heating has been established for decades and is as commonplace throughout the United States, France, Germany and Russia, as diesel fuel burners are in New Zealand.

Mr Prentice said the niche waste-oil sector was gaining momentum in New Zealand, mainly in industries but with increasing interest from schools and other groups, many of them looking to swap coal for a cleaner heat.

In Dunedin, Escudo Coatings' managing director, Scott Taylor, was last week replacing an obsolete diesel/oil burner with a new Omniheat model, costing about $6000 all-up, given he had an existing tank and the burner sat next to the electroplating baths.

He said the burner heated both the degreaser and rinse baths to about 50degC.

Crucially, the new burner could automatically sense the type and viscosity of filtered oil and adjust the burner accordingly, without having to be manually reset.

"It's the new generation ... it flies on autopilot. Way more efficient and less down time,'' Mr Taylor said.

While Fulton Hogan supplies the waste oil, Mr Taylor said the new burner and its efficiencies now gave him several oil options.

Mr Prentice understood the former Holcim cement plant in Westport used to take more than 50% of the country's waste oil to burn, but its closure now meant a glut of waste oil was becoming stockpiled.

"Getting rid of the oil waste product is becoming a major environmental issue for New Zealand,'' he said, of storing, transporting and disposing of the hazardous waste.

He said one business had recently contacted Omniheat, looking to get 36,000 litres of waste oil off its hands.

Fulton Hogan is now collecting waste oil and acting as a distribution centre.

The waste oil comes from several sources, including fish and chip shops, transport companies, hydraulics and transformers.

It is burnt under pressure as a fine mist at around 700degC, which Mr Prentice said eliminated much of the emissions; they were about 25% of those emitted by a car.

The super-heated oil, in turn, heats a thermostatically controlled water cylinder and the water is then reticulated into wall radiators, underfloor or wherever required.

Mr Prentice estimated a house conversion cost about $20,000 and, depending on oil source, could be run with no further costs after the installation spend.

Mr Prentice said an Otago swimming pool that had had to raise $8500 a year to buy coal, had recently installed the system and cut costs to an estimated $2500-$3000.

"Of course, that depends on whether you're getting your oil free,'' he said

An Otago hydroponic horticulturist had also installed the system, heating the water used to grow hundreds of thousands of plants, Mr Prentice said.

We have been making these up for our burners, what they do is diffuse the airflow and are excellent if your fan is too strong and blows the fire out.
The other thing we have found, some people find if you light your heater using just a bowl for some odd reason they can smoke, and we can get the odd one that's tricky to get going from some reason. Stick one of these in the pot, the oil will pour through the centre hole, the fire is in the centre of the difuser and blows out through the vents in the ring and acts like a gas ring, it clears up any smoke. I think it's because it concentrates the flame to the centre of the pot rather than flame burning up the side of the pot.
So cleans up smoke to nil instantly.
Burns like a gas fire but fifty times more power.
Starts easier and faster. 
                                                                              The heater gets hotter quicker.
                                                                              I have tried a couple of versions, but don't quite get the results these ones do.
                                                                              So if you need to do all of the above, then contact us and we'll get one off to you. $39.95nzd
                                                                              Courier would be $6.50 throughout NZ.
                                                                              I made a couple up today and surprised at the length of time it took to made them. 
                                                                              Note these work with fan assisted waste oil heaters.
                                                                             These come with all our heaters.

We have just buit a commercial waste oil blower burner unit to convert a wood fired steam boiler into waste oil boiler. The fan box slightly larger, and the pipe used is 75mm diameter allowing all the fans air to reach the fire.106 cubic metres of air per minute 12 volt 2.5 amps. The fans have a lifespan of 50,000 hours, however my fans been going 5 years still going strong. This unit comes complete with oil controller and thermostat.

 The end of the pipe has a deflector, to direct the airflow into the burning bowl.

It will be used to cook up pig food using steam.

Painted in heatproff black, and zinc blue.

                                                                              Priced at $699.00 NZD

                                                                                                                         We build then to suit you needs or your heater.

This waste oil heater has gone to Dunedin to heat a 40,000 litre swimming pool, Our thanks goes out to Lindsay,

We fitted 30 metres of copper coils inside the cylinder and built a manifold to house both coils so we ended up with two 25mm fittings to connect the pool to, we also supplied a very small 800LPH inline circulation pump with this heater. 

We are currently building another heater with two separate 15 metre coils without the manifold, one coil will heat a 200 litre hotwater cylinder which the hot water will be pumped from the cylinder to multiply radiators within the home.

The other coil will heat the house hot water cylinder and when that's hot enough a valve will open to fed the spa pool.

Buy doing this will reduce his power bill by over half, and yet the heater will take on all that work.

Thanks for all your support we couldn't do all this without you guys.

                                          This is it finished. 

We built this heater and tested it with firewood which worked, but I expected more of that heat to reach the hotplate but it didn't even  cook the bacon very well because the frypan base wasn't flat. So we have added the waste oil blower burner unit to it, and now it will cook anything. It now runs over 400c and boils a large pot of water in 3 minutes from cold lol. I cooked steak and onions & eggs on it last night very nice.

It will be finish buffed clean maybe a black paint job too. 

Video of it going above.

Extremely clean burning. Nothing but a heatwave exiting the flue.

No smell, no smoke.

Excellent for a cabin or small batch or even a cold garage you may work in.

If you collect it we will through in 20 litres of waste oil and, or an empty 44 gallon drum or both.


This has sold.

The wood fired heater/cooktop. Can take 3-4 pots at a time.Sold

It's been difficult to source 45 kg cylinders at times, however we now have a steady supply of good quality cylinders, so if you would like one, to build your waste oil heater, or waste oil barbecue, they are available from us.

Drip Fed Waste Oil Heating, supplies waste oil heater parts, worldwide, however it's mainly to the USA, Canada, Australia, Scotland, and New Zealand, and a lot go to the South Island of NZ even the Chatham Islands, we are open to orders from the rest of the world too, we'll work out the freight cost for you.

We're offering free freight on some items in our parts section, but allow 2-3 weeks for delivery, rather than the paid freight option, which is five days to the United States.

Burning waste oil, the thick black choking smoke has been reduced to nil, and now in 2018 is a extremely efficient clean burning free fuel straight from the drum, as in the video above shows, and capable in heating almost any area you put the heater into.

Cleaner burning than today's wood fires.

Twice the heat output of a wood, diesel or coal.

And the best bit IT'S FREE.


With the help of our electronic waste oil heater controllers with the thermostat, have made waste oil heating very safe.

There's no more fluxuations in the temperature anymore.

The dual timer controls the upper temperature so the heater now sits at 500c or what you decide set it at.

And the thermostat looks after the lower levels should anything ever happen, it will turn the oil & heater off.

So now we light the heater never needing to check on it's progress, and turn it off via the mobile app at night or let it heat all night too.

So my suggestion is don't buy a waste oil heater without a digital controller.

Or if you have a waste oil heater, get yourself a controller for your own safety because without one we all know, waste oil heaters operating only on gravity are very dangerous.

To give you an example, to heat our 3 bedroom two storied home throughout the year, will burn 3-4 drums of oil per year, which equals 

around 820 litres, this saves over $800.00 in 45 kg LPG bottles or propane per winter.

This is achieved with the waste oil heater setup outside the home, heating water in a small 7 metre copper coil, which thermosyphons to a 2.5 metre x 500 mm double skinned radiator situated inside lounge, this radiates a constant heat output of 75-80 degrees c. 

As the water cools in the radiator, it falls back down to the heater to be reheated, and sent back up to the radiator which completes the loop.

There is no pressure build up in the closed loop.

Correction on the no pressure build up, I lit the heater today to show a customer how it works, and noticed two small water leaks from crox fittings in the hot water loop. Didn't think too much about it at the time, and 10 minutes later bang, one of the crox joins pulled apart leaking hot water out of the loop onto the concrete floor.

So what happened

The air had sucked in through the leaks which built up pressure in the loop.

So after a lot of emails back and forth, and lots of plumbing help form a recent fire/building inspector/customer from the council. Thankyou C

We purchased an Ajax Valve and a relief valve, with a 3.7 metre head after plumbers advice too.

The Ajax valve connects to the mains water supply keeping the loop full of water.

The Ajax valve controls pressure in the loop, and the head of water on the relief valve.

So should water pressure increase in the loop, it will exit out, and the mains water supply will automatically top up with the small amounts of water which exits the loop, keeping the loop always full.

We have since been told that these pressure relief valves can and do fail, so we have removed it, and gone with the open 4 metre tall open vent.

The whole radiator is hot, which heats the house beautifully, to the point where it needs turning down in the evenings.

The timer oil pump, is operating at between 14 and 6 second delay, and pumping oil for 1 second.

One twenty litre container now lasts all day or 2-3 nights heating.

This heater burns clean.

The thermostat has been fitted, should the fire or in our case the water temperature ever drop below 40 degrees C the thermostat will kick in and turn the oil pump off, stopping oil spills. 

You should always have your heater sitting in a cut down drum capable in holding the same amount of oil as your storage tank ideally 20 litres.

These heaters can either radiate heat, or they can heat water too.

Once you start heating water you start dealing with pressures which get very hot and extremely dangerous, so you will require a

 Licensed Qualified Plumber to make your system safe.

We do not want anyone making potential pipe bombs with stupid plumbing errors, which can go wrong very quickly, and end up scolding yourselfs. 

So please take our advice.


They are very expensive, and they charge like wounded bulls, but it's still better than scolding family members.

Most Council’s require that ALL PLUMBING work MUST be carried out by a qualified licensed tradesman. I would either suggest that the purchaser find out, or we'll find out for you, their local Council’s requirements. Some Councils  allow homeowners to carry out limited plumbing work of a minor nature, this is a Government authorized statute in law. From memory there are only 4 or 5 local authorities that have this statute.

The Ajax Valve, necessary for reducing the town water pressure down to your loop pressure you need.

Thanks for your support.

Wifi gadgets, when it comes to waste oil heating we think is important to know just what's going on with the heater at all times.

We now have two wifi plugs connected to the waste oil controller & fan, one which I use to turn off the oil flow, then 15 minutes later I turn the fan off. Being wifi you can turn them off from anywhere.

 I just recieved a Sonoff TH16 today, which run through the wifi and displays a current temperature of the radiator in our lounge which is currently 75c. So now I can check the temperature anywhere, if the temp is too low or high, an alarm rings on the mobile and i can bypass the timer or the thermostat and turn the heater off even if i'm shopping in town. There's also a wifi camera. A common old smoke detector outside near the fire, so I do think we have all the bases covered now.  The Sonoff th16 is $40.30nzd should you need one. Can be use to turn appliances on and off at certain times and run the for a length of time, a very clever little white box.

We would love to hear your, comments, input, and any questions you may have regarding waste oil heating.
If your building your own heater we are here to help, we have years of testing, designing, these, so if there's anything you want to find out, like how to burn this oily stuff cleanly, then just ask, we are here to help anyone..

Waste oil heaters if left going un-attention without a timed controller pump system, can become extremely dangerous. 
using needle valves and wheel valves to control oil flow won't always work, why, because as the oil supply warms up the consistency of the oil, causing the oil to flow faster, if your storage container is full or near empty, even this affects oil delivery to your heater. 
By removing these variables and controlling oil flow with a pump, will turn these heaters into a reliable consistent heat source which we have found can't be accomplished satisfactory using taps.
What can also help, is if your heater is inside, keep your oil supply outside and vica versa.
The problem we see with waste oil heating, it's not if it can heat an area, it's controlling its heat output so it doesn't turn your cylinder red-white hot. By controlling the oil input to a measured set amount every so many seconds,, your heater will never overheat again. The timer pump units really does work well. A very worthwhile piece of mind, investment for your home built heater.
We have now added the thermostat to it, to control the lower temperatures.

We've built & designed a free safe heat source over the years, which can now be turned off by your mobile phone, so now you can heat everything for free, from your home, business, sheds, workshops, spa pools, hot water cylinders, radiators, swimming pools, aircraft hangars, glasshouses, chicken rearing sheds, even calfs milk. We even built steam boilers to remove honey wax from your hives.
So if you have something you need heated give us a call we would love to hear from you.

We operate in any currency you choose, thanks to Paypal. We can send you a payment request.

If you're living in the United States these heating savings can run into thousands of dollars.
I have a customer who brought a blower unit, said we saved him $25,000USD in Propane alone, every winter.
Not bad for an outlay of $193.00 USD. I can't believe the saving you people are coming back with, really are incredible, I'm so pleased this is doing exactly what we thought it would, save everyone money in heating and removing waste oil. from the planet
We now need to look into gasifying Plastic too although I think China has that sorted.

Canola, vegetable, olive, oils which are fine to burn because they are outside of the HSNO Act.
Engine oil, also a waste product, and they say a hazardous substance well yes, maybe if you burn it in a rubbish bin lid,, nowdays or oils are synthetic, still fine to burn in a purpose built heater. 
Eighty percent of the world's waste oil is burnt either for heat recovery, or generating electricity.
New Zealand produces 35 million litres of waste oil a year, a fair amount of it being burnt by Westport Cement, & hot mix asphalts, greenhouse growers, and a little wee wee bit by drip fed customers. I think the Huntley Power Station also burns it.
Our customers and ourselves have been burning oil for heating for around 9 years our family all in good health, no health issues, neighbour wouldn't even know we are burning oil, it's that clean. I asure you if this black gold was hazardous we'd know about it, and we certainly wouldn't be using it for heating, nor would any other business in town be allowed to use it.

In saying that you still need to be very careful with it, as this guy contacted us with these issues.
#If you are getting headaches, Feeling Sleepy, stop using your heater as it may be letting out carbon monoxide into the room.
We have just been talking to Andrew who converted his existing wood firebox, and the vents were allowing gases to escape into the lounge. Carbon Monoxide is a silent killer be very careful. 
Our advice, get rid of it today. He's building one of ours now.
Thanks Andrew.

This blower burner unit has been built to fit into and existing logfire. A hole is drilled in the side of the firebox and is fitted blower is fitted through the 55mm hole, the plates are then clamped up with the use of  bolts onto the internal fire bricks, and the outer casing of the logfire. This unit is off to Australia.



These totally change waste oil heating to a safe, consistent, temperature.

For better control of the oil delivery to your waste oil heater.

The problems we have with oil, is as it warms and cools, flow rates can increase, and decrease, even through a precision needle valve, there are differences in pressures in the oil line, even when the storage tank is full, or near empty, this is why this type of heating can be so frustrating at times. 

So by using this pump/timer system it eliminates these variations in the oil flow rate, and keeps the heater at a steady temperature without the fluctuations we found in the gravity system.

The timer can be adjusted to your heating requirements by increasing or decreasing the delay time.

We now sell this complete Dual Timer Pump Systems fully wired, plumbed up ready to connect to your heater.

The Dual Timer kit comes complete with a brass reducing bush from 3/4" to 3/8ths" with hose tail which fits your storage tank which also connects to the tubing, 3 metres clear plastic tubing,  S/S hose clips, 

12 volt 230/240 volt AC power adaptor, oil pump, and a dual timer, with full printed instructions on all 4 modes P1 P2 P3 P4. 

All fitted inside a plastic box or safe keeping.

The Mode settings. 

Mode P1 Start time.

Mode P2 Stop time, if you want the heater to only run for 4 hours, then it will stop the oil flow after that time.

Mode P3 Is the dual timer, which operates the pump for a set amount of time, and a delay time. We set ours to 1 second then stops for 9 seconds, and continues until you stop it. The time delay we find does need to be altered to different batches of oil. 

Mode P4 is a stobe light LED light option.

As the oil exits the copper tubing at extremely high temperature it changes into a gas (Gasification) and it's this gas which keeps the heater going, not a pool of oil burning in the pot. We have found there is no oil in the pot during operation, to prove this we used a pot with 5 holes in the bottom, sort of expecting to find oil exiting the heater, it continued burning for 15 hours, and not a drop of oil was captured proving gasification was occurring.

We have alot of customers wanting to get rid of their expensive diesel, gas & wood burning units, and change to a more efficient, free to run, waste oil blower, burner units.

These blower burner units heat anything from the larger upright Marshall boilers, to the domestic water heating double wall water heaters/boilers. We have found they will heat any vessel they are installed in, from the 9kg gas cylinder, to the larger 45 kg gas cylinder for the larger buildings. Basically the larger the steel vessel, the more heat it will radiate.

Although we build these to fit your heating needs, we have normally two types which work, they are the Straight Nose & Bent Nose blowers. Straight nose for existing fire boxes, marshall heaters, or where the two parts meet by opening and closing a door. The bend blowers are for cylinders where water is to be heated. These are fitted through the side of the cylinder into a pot.

New Zealand prices

The bent nose $399.00 nzd plus freight, $20.00 Nth Island $39.00 Sth Island.

Customer feedback from a blower burner unit.

Aaaaaaah the warmth. It's been running for a few days now and is excellent, less noise, less smoke, more efficient, more consistent output. Very good Jim 10/10.

The twisted piece of pipe is great, gets the fan out if the way, and the timer/pump will be sent for when funds are allocated, we’re now discussing putting in another radiator…

Many thanks


Hello Hamish, Wer'e just had another look at your website and had a good laugh. Seeing our 'twisted' blower unit. Now some of the facts aren't quite correct, after 5 months constant use, often with 8 radiators and two showers going simultaneously we had to say it's fantastic 20/10.

After 40 years burning wood and sometimes coal on various water heaters in different houses this is it.

The way to go to heat a house. Anyway about the timmer. lol

yes he got one.

Best Regards Graham.

As simple as unbolt the diesel burner, and bolt on the waste oil blower unit.

#Left is a video of the blower burner unit in action as is without it being installed in a cylinder. 
Shows the Dual timer in action too.

Grahams, Twisted blower burner unit now heating everything.

45 kg gas cyinders with door and flue holes aready made.

All you need is the burner blower unit to bolt onto the side of the cylinder. 

Comes with buring pot. pot stand,solid steel hinged door and flue housing.

$360.00nzd These are too heavy to export.

Delivery to your door.

Delivery time frame, depending on the item you order, 5 days, depending if the item or items are in stock.. 

Completed heaters sales allow up to 3 - 4 weeks.

From the 31st August 2016 Drip Fed Waste Oil Heating, stopped selling fully built, ready to light waste oil heaters, to New Zealanders.

Worksafe wanted $25-$30,000 to have these certified. And yet you can import any fire from overseas without certification, and that's ok.. 

We sell heater parts now, like blower units, fans, and power supplies, timers & pumps with electronics, WIFI controllers, empty gas cylinders, plastic tubing, copper tubing, electronic controllers, made to order, copper coil wetbacks, all available, to everyone,, so you can build your own heater. 

The blower unit bolts on to the side of any cylinder. The flue housing requires welding which we can do for you, should you purchase a cylinder.

Make contact we will be able to put you in the right direction. Email

To operate the termostat press the left button once and alter the temperature by the + or  - on the right.

It can operate both hot and cold temps but this option is H or C by holding down the left button for a couple of seconds and altering with the + & - buttons.

Hi Hamish, I put the dual timer kit, in two weekends ago and that solved all the flow problems! 

No more variable flow rates as the sun heats the oil tank, and good flow into the burner bowl all the time now - I used a timer and have found that a rate of "on for one second, off for two" is best 

It works so well I can turn it on in the morning and leave it all day with no adjustment at all - brilliant!

Here's the setup above.

Note the smoke levels.

The Oil feed Controller left.
Now with thermostat fitted
Certainly a must for any home made waste oil heater.
Timer comes pre-set 6 sec delay 1 second pump, this controls the upper heat setting and the thermostat controls the low temperatures so if the heater dropped below a set temperature the oil flow and the pump stops.
Stopping the oil flow after the flame has extinguest is very important, otherwise the oil continues to flow until your storage tank empties out.
No one has this option other than us.

WIFI controller.

We have WiFi controllers which come with a free download mobile app, to turn the heater off, or set the heater to a timer, which works from any WIFI or mobile connection. 

Excellent if you leave work and forget to turn it off. 

We still think the lighting should be done manually to make sure they its going.

We use two WIFI controllers one for the fan and the other for the oil supply, but you can get away with using one controller for both.

The WIFI is an optional extra which I find really handy Priced at $48.06 usd or $52.00 nzd plus freightBUY NOW

The next idea is a Wifi camera pointed at the heater, connected to your phone would be handy. So you don't need to go outside to check it at all. With the dual timer fitted there really is no need to check it anymore as we did with the graviy feed types.

Camera is ready to be fitted in place.

All our waste oil heaters can operate up to approximately 800 C cleanly, however we recomend 400-600 degrees celsius, with these temperatures we recommend to install fire safe surrounds, whether that be brickwork, suitable tin sheeting, or hardie board with a 20mm gap between the wall so air can flow behind the sheet, and 20 mm off the ground and the heater setup 500 mm away from any fire proof surface you have constructed.

The complete blower burner unit.
Pictured above
These are the burner units we use in all our heaters.
Operate similar to a computer fan, but a lot more powerful, they blow the oil into the pot making the oil burn cleanly. 
These fans are now Imported from Germany.
The fans come with a fan speed controller..
The blower unit will burn at a rate of 1.2-1.8 litres of oil an hour. 
238,000 BTU's or 7 kilowatts.
The above blower pipe, comes with oil line, fan & fan speed controller, with a 240 volt 12 volt power adapter, complete with needle valve.
 This can be fitted into any cylinder. Cut a 60mm x 60mm hole in the side of your cylinder set the burner end at 60-80mm from inside the bottom of the pot
 Give us the radius measurement of your cylinder, and we can weld the plate on the pipe to your measurement, making the blow pipe sit in the centre of your pot. This will then bolt onto your cylinder. Check out Parts to builds your own tab for prices.
All the parts are available to be sent world wide, just not our Gas cylinders as they are only for NZers. You can use old compressor cylinders or large diameter pipe from a drilling company just blank the ends off.

The blower burner after 2 minutes being lit. 

Little bit of smoke which can happen when there is too much oil entring the pot or your the air force isn't correct. Sometimes it can be the rag used to light the oil smokes. To clear any smoke, turn the oil off until it clears, turn the oil back on, but reduced rate or increase fan speed. 

You can see just by the flame colour if the heater is going to smoke, if you will see an orange/black darkish flame, it will smoke, so change the flame to a yellow white agitated flame with pointed tips you need to either increase the fan speed or the fans cubic feet per metre. The hair dryer, is great for testing, as it has three speeds. Not good as a fan full time, as they aren't rated for long term use, and can be very loud. 

Blower Fans.

 80mm x 80mm 12V 0.57A with wires to connect to. Positive Red, Negative Black. These are the only fans we could get the correct airflow, which makes waste oil heating, clean burning.  So, if your building a heater these work.

We can also supply the speed controller and 12V 240 Volt power adapter at an additional cost. Just ask.

The only retricting factor of waste oil heating, when it comes to long hours of heating is the buildup of carbon in the pot. Hard to see from this image, but after 12 hours there is approx a cup and a half full of carbon. The way to get around this if burning throughtout the night, is to change to a clean pot before the night burn starts. This will alter with different types of oil. Hydraulic oil seems to leave no carbon behind which would be perfect for long burning. So a business who services hydralic rams would be the ones to get your oil from. I have found a lot of water in this oil but tilting the oil container back from the oil outlet pipe will solve this problem. 

I had too many holes in the stainless steel pot which was purchased from Mitre 10, so i changed it to a flat bottom pot i had lying around the shed, no mater what i did when i lit it the fire smoked infact at one stage it went out. I dug out the old holy pot stuck that back in the heater lite it no smoke, why! Well all to do with the shape i surpose. So we use a kitchen mixing bowl either from a supermarket or M10 they work well but the stainless steel is very thin and will last 6 months, however at $9.90 it's still a cheap pot.

The Do's and Don'ts when it comes to waste oil heating.

Filter all your oil you intend to burn, this is important, never try burning it unfiltered the problems of blocking taps, and lines are honesty not worth the hassle and messy. If they block, you can use compressed air carefully, blow the oil back up the tube to the storage tank so any oil is contained.

Do use a gas torch to light the oil, it will makes lighting the oil a lot faster.

Do limit the oil flow to a maximum of 2 and a half turns on the needle valve or a thin steam just after a drip.

Do turn the fan on when you light the heater soon after you have a good flame going 5 seconds or so.

Do shut the door.

Do put 2 lengths of flue minimum onto your heater.

Do use a temperature gauge, then you can see exactly what your heater is doing at all times.

If running a radiator/s keep a temp gauge on the radiator, so should the radiator drops in temperature to say 40C from 85C you will need to go and check the heater, as it may have run out of oil, or the ash has built up inside the pot, turn the heater off, and change pots to a clean one, and relight.

Clean the flue if soot falkes are exiting the flue when you start lighting your heater. Clean the flue after 200 litres of oil burnt.

If you don't clean the flue, soot will block the airflow snuffing out the flame, and if your overflow oil capture is non existent, then you'll be in alot of trouble.

Don't ever light these heaters with petrol Never light the heater with petrol if it is still hot, you'll get about a metre away from the heater before the fumes ignite with a boom. The flue will end up in your neighbours, your dog will turn from white to black in .5 of a second. 

Don't over supply any heater with too much oil, or the well known Chernobyl effect will take place. This it when the heater starts to roar, smokes, and turn the heater red including the flue. Should this ever happen turn the oil off, block air inlet holes and sit it out. 

Remember 1 litre can burn for an hour. Image below not vey clear sorry. The fan forced heater don't seem to do this however care is needed so it never happens.

Don't leave it unattended, no different to an open fire. Unless you have a oil feed controller.

Keep very close eye on these heaters when they are new, they will train you, rather than you training it.

We have had eight years operating these heaters, we know how they should sound when operating correctly, and you will also become tuned in to them when operating.

This will take you a couple of weeks to learn its ways..

Do it right, and you'll get to enjoy all the free heat. Its simple, never oversupply oil to these heaters, and they will heat your world for free. Use a oil controller dual timer, pump system, to be safe. Wifi controls will also make your life easier.

All available right here. Thanks for taking your time to check use out.

Tommy lives in USA and came to us wanting to build a fan forced waste oil heater for his shed, so he purchased our plans, from which he has now finished this heater shown in the video above, and it's a big beast. Love the additional spark plug option not included in the plans, the second stage burn he fitted, to it just to keep his mates guessing, what on earth he was building. 

He purchased the fan box kit only from us, now look at it. 

Thanks Tommy for sharing with the viewers, excellent work.
