Hi Hamish yes its in the shed and going good been going 4 the last 3 nights and heats the shed up good and nice and quiet.
Thanks heaps Tim
Ken's huge drip fed waste oil heater finished and sent.
This is going to be his pool heater, a very big unit. For serious heating requirements. Pool size 50,000 litres.
Has a ladder wetback below image inside it.
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.
The Man Cave with another heater packed and off in the
Waverley. Thankyou Ken.
A few heaters wrapped and ready to be delivered.

Never pour water onto an oil fire, it will explode to 30 feet high.
Use a powder Fire Extinguisher only.
NEVER EVER USE WATER.
Rain is fine as it doesn't enter the fire.
Forget Energy-wise tips and tricks in saving energy, this is totally free energy.
We have designed these heaters/boilers that heats your home for free.
Yes you have read it right Free.
Unheard of in these days especially when our energy costs are so high, and climbing every year.
Unlike solar heating, these keep you warm when it's freezing cold, cloudy and raining.
These heaters/boilers run on waste oil or canola oil and are clean burning.
They run by gravity fed.
So no power & no fans.
It can be setup outside with hot water heating you hot tub or radiators inside the home or even your hotwater cylinder all free.
To do this the boiler need to be running between 250-300 degrees F.
Costing not much more than a load of gum firewood to purchase this unit, will heat everything you ever needed heated.
Whatever you pay in heating over the winter months maybe, $700.00
these sell at $550 plus freight.
You are most welcome to collect one anytime.
If your good at steel work, and you can cut steel and weld, like a lot of guys are, buy our plans
$27.00 so cheap giving away my ideas.
We want you to be warm for free, it will take you 3-5 days to build you'll never look back.
I see the neighbour outside cutting wood for his fire what an act eh. He looks over at me thinking that looks too easy.
And he has a spar pool, we could heat that for nothing too.
A lot of farmers/garages and business have waste & canola oil sitting in drums in your backyard or around the back of the sheds, not knowing what to do with this stuff apart from costing them money to recycling it, so now you can heat whatever you want with it, totally free.
Instead of it leaking into the ground and waterways.
Convert it into heat. Get rid of it.
I heat my whole 3 bedroom house over winter consuming 310 litres of waste oil and that's all.
That's only one and a half 44 gallon drums.
"These are cleaner burning than most wood fires."
You can purchase your new waste oil heater
Here at Drip Fed Waste Oil Heating, we design and construct waste oil heaters for your heating requirements, large and small, for home heating, hot tubs, spars, 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.
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.
I admit it's a little underground at the moment, yet 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 now can 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.
*Yes the washing machine housing in the image below is going to become red bricks asap or money allows. It is keeping the heat off the corrugated iron I must say. And it now has a roof over it now. Water and buring hot oil don't mix at all. Always have a current powder fire extinguisher close by.

An email from our customers:Thanks for this Hamish, - Brad here from Melbourne Australia
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 very cheap to 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.
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
400 Fahrenheit 35 Celsius
500 Fahrenheit 40 Celsius
550 Fahrenheit 45 Celsius
600 Fahrenheit 50 Celsius
These are the temperatures I get from the oil heater and the radiators heat outputs.
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 plumped 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 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.
Typical eh the dayyou pull it out to do maintance, its freezing cold that night, had to turn on the gas fire still wasn't as warm.
Same picture as above but running at 450 degrees F at night, heating the water.
*CLEANING YOUR WASTE OIL HEATER/FURNACE.*
With my heater in images above 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.
Not good for the wife's washing at all !!! :)-
The other night the fire snuffed itself out it got that bad,
this morning I had a clean up
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 at all, as it's all kept inside the furnace/heater,
So maybe a clean once a year maybe good advice to you guys that have purchased these heaters, and how have built there own from plans.
That's about the recommended time for a wood fire, so as we are looking at "clean burning" it's a good idea.
This was my 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 too powerful for inside my home so it's been sold.
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 build up ontop of the water, not too much, but enough to startup my own Chernobyl reactor with that sound of bacon cooking.
The temperature whipped up, and the smoke became dark, out of the flue like you were burning tyres, and stand back, turn the feed off quick. 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 buy now, with all the experimenting stages, had a few of those, but with this big oil heater. It started blowing smoke rings out the holes in the tube, very impressive, luckily it is installed outside, for my sake. So don't let the oil build up at all or look out.
It then went fine when it settled down with not a drop of oil floating in the pan just glowing ash.
I must say that the water trap works so well, I haven't ever had that problem again.
These are available as a pool heater wrapped with 60 metres of 15 mm copper tubing running at 450-600 Fahrenheit will heat any pool.
Designed to operated 24/7 burning up to 1.8 litres per hour would burn 1, 44 gallon drum of waste oil in 5 days.
Priced at $1300.00NZ dollars.

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.

Installing Solid Fuel heaters
Info for flue setup and instilation.
The fire needs to be that hot to heat the water for the radiator as the heating pipe is only a 150 mm in length x 2 piece of 20 mm copper pipe that is getting hot. If I ever remade it I'd put a coil of copper tube on the outside.
If you put it inside it will collect soot and the soot would build up and the efficiency would drop quite considerably. The soot would act as an insulator stopping the water reaching it's maximum temperature.
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
40 degrees C and that's plenty to heat the whole house.
Thankyou to all that frequent this website.
I do hope it is really helping people with their heating situations.
If you are building one from the images on this website and haven't purchased the plans, that's fine, and you can't quite get it going right or smoke free, then please contact me I maybe able to help.
Testing the new model
photo's out soon
I lite my heater last night, it went it up to and over 1200 degrees Fahrenheit
(that's 648 degrees Celsius) the tube was red hot and the gas bottle too became cherry red and yet it was totally smokeless and safe, I did turn it down but it did show me that these heater would heat a larger areas than just a house.
Just amazing amount of heat.
With mine being outside I measured 2 metres out form where I could feel the heat coming off it, and it was a gusty windy evening. It had the hole outside warm.

Thanks for helping the waste oil heating team.
Mobile service station Havelock North NZ
A new design on it's way shortly, been working on it today. Takes three gas bottles to make, and will be totally enclosed. It will be steel in colour as it gets to hot for paint.
Hopefully get near finishing tomorrow.
May have a Video for you all to view.
I am still testing it, it is smoking a little at this stage but hopefully in the next few days we will have that problem solved. I also have to buff off all that old paint a bit of a mission. This is an excellent heater no flame can be seen while going, as it all inside and contained the shell. We have stripped the paint off so it's all buffed steel at the moment.
We are going to paint it black tomorrow, and when it's all going correctly it will be back on the website. Then it will be for sale as we haven't had any offers, however selling it on Trademe it will go.
Similar as Gerry on youtube but no Pyrex bowl. https://www.youtube.com/watch?v=cYxtNRKj1Es
The heater video above is an ideal inside the garage type heater. You won't see any flame and it's going to be totally enclosed once the door is hinged, it will be great safe fire. Still testing it today going to try and get it smokeless. It will be finished in matt heatproof black paint
It will be for sale shortly once all testing has been completed. Still working on this one it is smoking more than I would like, so lots of thinking on how to eradicate this problem. But will be for sale asap.
The next project in the pipeline.
Small Bus drip fed waste oil heaters.
Small gas bottle heaters with a cover to catch any bits of smoke that could come from the second burning stage. On legs as normal maybe even a drum cut to from as a heatproof backing. Watch this space. I have all the parts just time and energy needed.
And a nice warm day.
Well Wel Well it didn't take long, about 3 days, and someone has found the warmth already.
I'm going to put it out their, If there are people out there that are interested in helping us, and become part of the team in taking this free heating to the next level. Please get in contact. We would love to hear your ideas and what can be done to improve our system.
I think we have something quite special and unique. Once the initial cost of the heater, which at $550.00 isn't that expensive compared with wood fires.
You have for the rest of the fires useful life a totally free clean burning heating system. Rather than paying out for expensive firewood year after year.
Business for sale

Your business customers will order via this website, and can pick up their New drip fed waste oil heater from your business, paying you direct. You would have to be able to build these to a high standard, be good at welding, and have them in stock for sales via this website.
Costing from $2500.00 NZ dollars to purchase this type of business. You will get permission to reproduce our design and produce and this website with your address & email so customers that live in your town/ country, can pay & pick up direct from you. I need someone in Spain to build these heaters.
I can't freight these world wide because of the freight costs from New Zealand.
There would be no commission on the fires you sell.
The plans wouldn't go with this business.
Should you be interested please get in contact via the form below.
New Zealand has been taken sorry.
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 www.trademe.co.nz.
The plans for this heater is now available through the Purchase your heater and Plans tab at the top of this page.
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.
Just built for Aaron. To be delivered next week.
The inside the garage/bus version same as above but has a cover over the holly tube, and a kettle warmer. The flue is just an example, still not quite completed as painting is next, with legs and pot holder still to come.
No Plans for this one but can add the skirt to the existing plans if you want.
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 $600.00 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. Not a huge outlay $27.00 NZ in any language.
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 for only $25.00 NZ dollars, 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.

Starts Tomorrow Morning
The next big heating idea starting in the morning although I have already built the burner unit today.
I'm using a 44 gallon drum with two of these 150mm holes to house two flues running the length of the drum so air can be heated up via the burner.
The hot air will blow through the tube warming any building, recycling their existing air.
I could pop a fan in the tubes for more air circulation but hoping the airflow will be enough as you know how I feel about using power.
The burner will be mounted under the drum and a flue out the top.
I will also pop a coil of copper inside the drum for hot water heating.
The idea is to heat larger areas like glass houses and that type of buildings for free.
I have another way to heat your home for next to nothing, and cheaper than my waste oil
heaters, but it is not a turn on and forget system.
This is how it works.
When the sun comes out, it will warm the roof cavity up very quickly especially metal roofs.
This system is really only good for during daylight hours.
For an example at the moment my house inside is reading 22 degrees the roof cavity is
reading 27 degrees. If I turn it on and leave it till the temp in the roof drops past the inside
temp then I turn it off. If you where smart you could add a thermostat to the system.
Which I have but not wired it up as yet.
That heat is trapped inside the roof area and it stays there for some time.
It's a simple as putting a fan up high in the roof cavity and ducting it down through the
manhole or a plastic air con diffuser in the ceiling. Add a switch in the wall so you can turn it
on and off. The fan size needs to be 200-250mm diameter.
You will need a thermometer that reads the roof cavity temp and the inside the home temp.
This way you can see the temperature in the roof is far hotter than inside the home.
You have free heat well, but still costing to run the fan.
They call this a DVS or a HRV without the heating ability when its cold.
These systems DVS and HRV cost thousands. Last quote $2800 approx.
Mine only cost me about $250.00 all up and it has it times when it works really well.
Unlike a HRV, don't leave this going all night, you'll wake up frozen.
Hope it helps.
It can be as easy as using one of these bathroom fan system available at Mitre 10 $115.00
Or just a fan mounted in the ceiling. So simple. If the sun comes out, and your cold turn it on.
If you have an empty gas bottle or out of date one and a pot the wife won't miss,
and a Brake Rotor laying around the house you're half way there, all you need is steel legs and a $10.00 tube, it that easy to build.
Purchase the plans I'll show you the Techie bits, and you too will have a free heat source like these guys, and soon yours will be up here in lights, for everyone to see how good it looks.
I will also help you with the build if you wish. If you don't like the idea of burning waste engine oil, then burn canola oil there's very little difference and still burns clean with no adjustments to your heater. Come on cut your heating bills to zero, stop pay out every month.
