Drip Fed Waste Oil Heating

Click here to edit subtitle

It's Getting colder here in New Zealand, Daylight saving has gone back an hour, give it a week or two and it will be cold again. I had my waste oil heater warming the house last night, nice and warm. The heater stayed on 350 degrees F all night, it was perfect.  Just by ducting the hot air it produced enough heat to heat the house up. Heat rises up the stairs heating the house and drying the cloths in the garage. Turning a waste product, which is normally not wanted, into a free energy source, to heat homes and water totally free is just brilliant If I can say myself.

If there is anyone one out there, who knows how to turn these types of heater into an energy/power producing system either via steam or other mean please get in contact. We would love to hear your ideas. 


These Waste oil Heaters are slowly taking over, the existing wood fire heaters in homes and shed's all around the world, I know from the amount of people that check this website out, and purchase the plans, it's growing fast.


I admit it's a little underground at the moment, but there's a lot of interest in these "drip fed waste oil  heaters".

 I now can trust mine, so once set to a temperature it won't alter from that all night and it's going to be all night soon. I turn it off at the tap, at night and go to bed without checking it is out now, it is that reliable.

Selling the complete units are a bit of a hit with my customers. There has been no complaints to date, which I find is great.  Mind due, who wouldn't be interested in free heating, after paying out dearly for all these years. Time for change maybe. So long as you have the ideal area for it of course.

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.  

I did an experiment last year with a bowl, lid & a flue (as above) and not one ounce of smoke came out of it, I couldn't believe how clean burning it was, there was nothing coming out of the flue but a vapour. This was because not a lot of air got into the firebox resulting in a very clean burn. So I have posted the results below in the video. I've welded all the holes up, look how she goes now. But that's only two lengths of flue remember. It will change again with more flue added.

It's now 11.20am and I have welded the holes in the tube, lit it,  but it started making that droughty sound which meant starving for air. Smoked like I don't no what, so I drilled 3, 10mm holes in the side of the rotor and welded up 4 of the holes on the rotor, looked up and no smoke at all, it works. It's a very tame fire and and a tall flame and it's still getting up to 200f easily and I would say uses less fuel not that that matters. I have placed the vid below for you to view. However now I have added 6 meters of flue pipe that's changed again, it now requires more air holes.

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 it has to be free too as I'm never buying waste oil at any stage

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. 

The say firewood makes you hot 4 times.

 These Waste oil heaters with there water heat capibility are ideally suited for swimming pools, Spar-pools, batches, hot-water cylinders, radiators, underfloor heating using existing piping & pump, garages, hot houses or man caves, chook house, even camping, hot showers, or just where ever you require FREE heating. Free heating unheard of a few years ago.  

The oil that can be used in this type of heater is engine oil, from cars, or trucks, transmission fluid, diesel, fish & chip shop old waste oil and fat. 
Basically any oil will work in this heater and the best of all is all of the above is available locally and totally free.

How it works, oil in container is fed via gravity to the needle valve tap where is drips into the fry pan at about 3 - 4 drips a second. This will get the heater up to 100 Degrees C quickly.

When it is fully alight and the oil is burning hot, looking closely at it burning, there is nothing at all in the pan, but fire, but it looks like it is gas which is feeding it, when infact the oil is changing to a gas, quite amazing to see it auction.
It will burn one litre of oil an hour approx, at 200 degrees C till the oil either runs out, or you turn it off. 

The wetback will heat 40 litres to 50 degrees with the heater at 200 degrees, per hour.

It's the kind of heater, I now trust, I can leave it for hours go into town come back and it's sill the same as when you left. It doesn't alter, once you have it set to where you want it, and it has to be this way. I do use a brass needle valve for the oil feed. Needle valves makes waste oil burning safer, a real must. So if you are making one just from the website please invest in a needle valve, they aren't cheap, but well worth it. It has to be totally safe, not only it's burning but the place you install it.

Even though it's safe you still need to be careful. I had it in my new house and I watched it like a hawk and there would be no way of sleeping while it was going, however now it's outside in it's final position, and it's going to be keeping the radiator going 24/7, I'm fine with it. I'll sleep like a log now.

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. Thanks Doug

Started plumbing in the Radiator. I purchase 5 metres of 20 mm copper pipe.

This has been my waste oil heater unwrapped for the past two years.

It has been wonderful, all that free heat, at times too much heat, just too powerful for inside my home so it's been sold.

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

Thanks Doug Hows it going for you Doug.

I started my hot pot 9 heater tonight, popped in the starter fluid, turned on the oil flow, and within a few minutes realise it was sounding wrong, the oil had build up in the pan, not too much, but enough to startup my own Chernobyl reactor. The temp wiped up, and the smoke became dark out the flue like you were burning tyres, and hello stand back, turn the feed off quick. The wife sticks her head out 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 the experimenting stages, had a bit of that but with this big sod, however that was in the garage. 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.

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 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 www.youtube.com for more of the begining videos.

http://www.youtube.com/watch?v=TALhsTcfy9E thiis was the testing the smoke stage.

http://www.youtube.com/watch?v=jk-wrwdRZac The finished video same as above.

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. 



These Hot pot 9 heaters are for sale on www.trademe.co.nz should you wish to purchase through them. 

Waste oil heating free heat complete with wetback.

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 oversea's looking at this website, and I can see why, winter is approaching, heating becomes a major concern.

I have priced, to send a waste oil heaters over to USA, the freight price is for one unit is $600.00 NZ dollars, just not worth it. So get out in that shed today and start making one for yourself. Purchase the plans first.

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 $15.00 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.

Thank's to Ozzirt Ozzirt, Jack of all trades JackofallTrades383, Rm Duck RmDucks you guys are amazing Thankyou.

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

Regards Hamish also known as Fireman Jim on YouTube
