The home of the blue flame waste oil heaters. 

We've made quite a few designs, but we have found these blue flame waste oil heaters, simply are the best.

If your looking for alternative heating source that's free to run, clean burning, and doesn't require much of your time, run for days, then you've found it.

The heat output of these heaters is incredible.

The cyclone type blue flame heater burns cleaner than any wood fire, and under control with our waste oil controller they will never smoke.

Now that's a big call, I know when it comes to waste oil heaters we know, they can do, but these don't smoke because the circling of the flame.

Check the video's below.

Our home waste oil heater which installed outside, yes outside, we have just changed it over to the blue flame cyclone type, which heats the radiatorin our lounge between 68c & 80c and sits there all day, because it doesn't drop below 68c so it heats the house easily, I love it. 

This radiator now heats the lounge, kitchen, hall, two bedrooms, stair well, and two bathrooms to 25c the old system would only heat the lounge. It's going to be cold tomorrow, I can't wait to light it.

We have heated our home for 15 years, for free.

We are currently having 20% of our 45kg heater plans, now $14.48usd or $20.00nzd.

This is the cheapest way to start your waste oil heater build especially if your in the States.

PLANS for the 45kg Heater.

If you've looking for an alternative form of free heating, to heat your home, workshop, farm shed, or pool.
Apart from the initial cost of setup, like any heater, the heating part is totally free, unlike 100% of heating systems that costs dearly. 

  Holcim cement plant in Westport used to take more than half of New Zealand's waste oil per year to burn, its closure has meant a glut of waste oil was becoming stockpiled. If every there was ever a time it's now. 
And I have heard garages are now being charged to have their oil recycled, 10 cents a litre and $75.00 a pump out.
They'll be pleased to see you. 

If you are wanting to purchase anything from the website, it can be done on this website, however if you have no joy, email us, we'll get intouch, with prices, freight is extra, we would love to hear from you.
Email address. 

 They're designed to be installed outside, heating water, heat the home, pools, radiators, hot water cylinders, 
dairy sheds, glass houses, motel pools, brewing, and underfloor heating.
 We have supplied alot of engineering workshops with these, fitted inside for radiant heat also a few aircraft hangars.

The power usage is minimal.
Adaptors are used to cut down the power from 210-240 volts AC to 12 volt DC 10 amps.
For off grid situation they can also run from a 12 volt car battery.

Plans aren't the blue flame heater.
# For our overseas customers, we recommend you look at the Waste oil heater Plansto build your own heater as many have in the parts, using what you may already have, this would be the fastest, and most cost effective way to get into waste oil heating, or by purchasing our pre-built  blower burner unit  with the waste oil controller unit from us, this way all you need to do is cut a 2" square hole in the side of your logfire box and drill 4 bolt holes, connect the oil up to it, sit the pot provided under the blower unit and light it, and away you go. Or you can build the blower unit.
We also show you how to build the 45 kg cylinder heaters which these burner blower unit fit. We are here to help get it right first time.

                   All overseas customers use PayPal for buying from this website. We find it the safest way to purchase online.

                                                                           We as the seller get no information of yours from PayPal.

Apart from the payment has been made by you and your contact details you left.

We build heaters with multiple copper coils, depending on the amount of water volume you wish to heat. 

We have found these heaters are very easy for customers to operate with the waste oil controller unit. 

The controller unit does just that, controls the heater so you can trust it.

Gravity fed heaters are very dangerous, we don't do them. Don't recommend them.

Any questions on waste oil heaters please feel free to email us.

The idea was to get this to the blue flame but my thought is the fan needs to be stronger. It did go blue when I lit it, but didn't find that again in the three hours of burning. Luckily we have many fans to try. I'm happy it burnt clean and didn't smell. 

This is for sale $750.00 NZD email us should you wish to purchase. Will fill up the oil container for you too.

This is in Hawkes Bay, New Zealand

Second attempt with this heater was slightly hotter but the flame was on the verg of changing to blue. It's funny the flame goes almost clear before changing to the blue colour. The other different thing with this heater compared to the ones we have been building, it needs a pool of oil, were its gasifiers. So it doesn't go into that Chernobyl burn off, normal waste oil heaters can do, but it will smoke slightly if too much oil is poured in. But with too much oil the flame will climb up the cylinder instead of sitting at the bottom. Turn oil off until it burns off then on again.

We are building another one with stronger fan today. 

Well, here it is, slightly stronger fan managed to change it to blue..

The breeze and the introduction of oil to the heater change it slightly but all in all successful. We are going to put a coil in this seems so much heat over 500c and on a 29c day it was very hot. We have since covered the top with a metal plate disc so you can cook on it, and fitted a flue housing to it to complete it.

The house heater and findings.

So I've been using our home heater for the last week or so, and over that time found the new blue flame to be perfect.

I light it with a cup of diesel and a piece of paper, turn on the oil, then the fan, away she goes. Get to temperature quick. 

I've found the temperature of the water which is going up to the radiator is 68c to 85c all night, and because it doesn't drop below that, the house gets warm and stays warm. The heater never alters, never smokes, no soot anywhere, it's brilliant, it runs like a gas heater so sable.

And turning off is quite a quick, turn off oil, the flame quickly extinguish turn fan off.

   The only thing is the ash of the oil I'm burning needs cleaning out after a few days. But considering it's heating the house for basically free it the least I can do. But using hydraulic oil didn't build up at all, so it could go all winter. 

We have four or five instock various sizes, call in and see them and get one in before winter. 

Blue flame heaters, How these work is by 1" of oil in the cylinder, this oil then heats up and the gases given off the oil, is what burns giving the blue flame. So it is gasifying the oil. The flame is in a constance cyclone at the bottom of the cylinder. 

I had seen these a few years ago, and never thought it was possible using our waste car engine oil to reach a blue flame, and thought they where adding meth's to get that colour in the flame which isn't what we are about. But after the second time we built one success, it was amazing to see this lovely blue flame. My second thought, was is the blue flame hot enough, it heated that 45kg cylinder up in minutes peeling paint off at it reached 540c so yes it was hot enough, in fact couldn't stand next to it for long. Filming was an act, as the heat it produced was so hot i couldn't hold the camera over it for long. Thought I'd damage the phone. It was very clean burning too. There was nothing on the bottom to smoulder on so no smoke during and at shutdown. Hydraulic oil is best, you wouldn't need to turn it off over winter.

I am extremely over the moon with these, they are  excellent. They don't do any thing nasty to you, like smoke or smell or get out of hand.

They are very boring and can be trusted to stay at the temperature you set it at.

This will be the new blue flame waste oil heaters, with & without coils the heat water.

As it is finished testing we are yet to finish it with the silver heatproof paint job.

A perfect size to heat spa pools stands 600mm high 800mm long x 380mm.

Would need concrete to sit on as the bottom of it is where te heat is.

It is amazing the heat that it producers, I connect the garden hose to the coil and turned on full, although water was pouring in to the oil and the flame couldn't to full temp, it was still heating the water. I soon stopped it too much water in the oil. But we are going to test the heating output and give figures of water temperatures in and out. 

This is up for sale For $750.00nzd as heater only.

Mine has a wood foundation with steel over it for the fire proof site it smells of wood burning beautiful. We have to fix that but until we do it has the garden hose with a small trickle stopping it from igniting the wood.  

Re-light this heater today after finishing it, but used the wrong burner so it didn't turn blue but it certainly did fill the cylinder with flame and clean burning.  Running just over 530c was tempting to throw a steak on it. I could image how good it would be to heat that pool with a coil fitted. I don't think these even need a flue there burn that clean. Does stop flame from coming out the heater. 
Remove the lid of the cylinder first, degassing it first, making sure it fits the lid you have for it.
It had to be a level &  straight cut.

Build the burner and fit level with the top.

Fit the lid or check it fits. Note no flue as yet.

Fit the fan to the burner bolt the to together & test . Attach heat guard so not to melt the plastic fan. Drill 10mm hole near base for to oil to enter the cylinder. I made a housing for the copper tub to fit into. Fan far to small to run it. 

Note the above video is not ours, be what we are trying to achieve. 
The oil is gasifying and the fumes are what are turning blue flame. Also there's no fumes.
Well the results weren't the best, felt the the fan wasn't  strong enough, so we have a bouncy castle fan we're going to fit to it.
That should do it. 
Ok bouncy castle fan fixed it we now have a blue flame heater run from thick waste oil.
Success :0) 
I ran it from 11am until 8pm, burnt thorough 25 litres of oil approx. for 9 hours that's 2.7 litres an hour, and there's no smoke at shutdown.
After some 20 hours testing of this heater these are our finding.
Fan too big for the likes of home heating, more commercial heating. Have built another with fan has less noise yet still produces enough heat. 
No smoke non, over the 20 hour test,  even if over feed oil or shutdown.
Doesn't smoke when burning diesel. But flame turns orange until diesel is burnt off.
Burns without the ash build up. And because of this no there's smouldering when turned off.
Extremely stable, sits on 500c  Nice and hot.
Ideal for long burning 24 / 7 
Burns more oil 2.7 litres an hour but we aren't saving oil.
Lovely blue flame .
Gets very hot even at startup.
No copper feed nozzle to get blocked. Oil is feed in the bottom of the cylinder.
If oil is allowed to drizzle back down the copper tube i'm sure it would block sooner than later. No problem to clean it just pull it out wipe the end.
The best.
This is for sale at $2500.00 you would want a large area to heat with this heater.                                                                                                   If your wanting something to heat a large workshop this is the one.
                                                                                       We have more with smaller fans on from $1178.00 heater only no coil.

This heater, after abit of thought yesterday we aren't using, because i have a copper coil spare didn't quite fit the od measurement so  made a total new heater that fitted the coil. We are lighting it this morning  and will post a video on the outcome. Hopefully enough to heat is pool below. We have adjusted the air holes which was wrong because there are too many so am welding those up to get it back to what it was.

We have found a use for this small heater which I put on the shelve for quite a while, our ibc container hot tub currently needs it, I removed the top of the ibc container today, going to put palings on the outside to look spa poolish.  Heating pipe outlet & inlets to be fitted so is a pool filter. Yet to put the coper coil around the 6" pipe for the water heating. Watch as is completed over the next few weeks.

                                  The pool, now has it's steps, we made a steel frame then screwed the boards to it, then bolted the fame to the pool.

It also has a level block base on a sand foundation to sit on 1600mm x 1200mm.

We have insulated with bates, pack it between the pool and the timber to keep warm.

 Next it to fit the heater to the 1" pipes this week. Clean it out and fill, we'll be using pool chlorine tabs to maintain it. 

Also a pool filter system we have from the old plastic pool.

With a lid on the top, keeps it very clean.

I've been in it 5 times over the summer and very nice. Plenty of room for two adults.

Well worth the effort.

Most expensive parts the timber and blocks and chlorine.

Waiting on the painter to finish her job.

I first imagined it to be abit like this, but not so. lol.

We have all seen the Safety Concise  Australian with his waste oil burners on YouTube, this is one of his ideas,  I wanted to test it. We built it today and am going to light it tomorrow.
From what I've seen they are very impressive with heat output, however the smoke levels are a little unknown  so want to see if we could use the idea in heating water for pools.
tested it however the smoke levels not good, plus the burning of the paint never helps, but will fix that and give it another go.
It went ok but as i didn't weld or seal the area where the pipe goes into the cylinder flame blow out there so we lost alot of flame which meant to be exiting the flue pipe. 
I've since removed the fan and replaced it with a bouncy castle fan  OMG.
Well we want heat, and that fan produces it.

My thought if it works clean, to fit it in a 45kg cylinder with copper coils in the top of the cylinder for larger water heating. The flame will blow about a  foot out of the pipe on the 9kg gas bottle.
This is a video of what I hope happens.   https://www.youtube.com/watch?v=bMmHOPlsSnQ

This worked really well, infact quite fighting the power, and the heat output was quite something and clean burning.  
Not to waste this amazing energy, our thought for this burner unit, is to work as a pool heater, so a 45 kg cylinder lying horizontal on legs, with this burner mounted under one end of the cylinder in a 75mm hole, with the flue mounted at the other end. In between the two there will be coils of copper not necessary coiled,  but in the pancake coils they come in, mounted to the top of , but inside the cylinder. I think  this would create a huge volume of hot water which is needed for pools. The heater would have a door at the front which will open the whole rounded front of the cylinder to access inside the heater for lighting. The burner unit would be removeable incase it required emptying  ashes etc.
The blower unit will lye inline with the cylinder but under the cylinder with the fan end nearer the flue end of the heater. Should be a vey tidy unit when finished, however we have a few of the other heaters to build first before, we can go onto this unit. Looking forward to getting into it.

               The results as above experiment, a very aggressive heater, very powerful, running at 1/3rd  speed. 
The flame going into a 45kg gas bottle should be safe. 
                     End of the day it worked better than expected, the heat it put out was incredible.

Next year we'll be looking at developing, this burner unit further, but instead of it burning vertically it will be horizontal, going into the end of a horizontal 45 kg cylinder on legs, with either coils or straight copper piping for the heat exchanger.
This flame seems to be three times the power output as the current units and as these pools are getting bigger & bigger this is what we need to look seriously into. 

We are trying to eliminate the charcoal build-up so hoping to run this for half a day and see what it does. Just testing it first before putting it inside a 45 kg heater.
We have left the bouncy castle  blower in the shed for this one and using our fan.
We had a oxygen cylinder here so removed the top for the pot. Nice and tall.

This one worked well too, and I found if you over feed it with oil it doesn't matter too much which is a change.
I have a large cylinder we will fit it into, once the above has been built and tested.

 Testing of other types of burners.

This is our current heater that heats the home has been upgradd to a blue flame heater.
The heater above is heating the 2 metre long radiator in the lounge direct from the copper coil via a circulation pump.
We have a sensor on the radiator which give us a temperature reading of HI, which we know the radiator is running over 75c, the room temperature is 21-22c and rising, outside is 10c. Very comfortable inside, have really only lit it 1/2 an hour ago, so it's doing well.
Now this heater runs for long hours probably around 10-11 hours today, so it's not a 5 minute wonder like the YouTube heaters you see. 90 percent of them are heating nothing and aren't being used to add warmth to a home or pool. Most are just flamethrowers heating the ground. We are more into using that free heat to save huge amounts of power.

We have now acquired two of these compressor type oil pumps for pumping oil out of  drums. Absolutely amazing bit of kit, if you ever get the chance to get one, do.

No mess just never walk away when filling any container with waste oil, never. These pump 50 litres a minute, if the tube bounced out of the drum what a bloody mess. Am to fit the handle later this week.

15 minutes via a 3/8th tube filled a drum of waste oil and has a filter at the bottom of the pipe, All made of stainless steel, beautifully made.

I see new ones on Trademe selling new one for $1500 & second hand units around $500.00 - $700.00.

Yeah abit expensive so ask your local garage if they have one, as they no longer use them because, the fuel companies are making them change to their new flash black units they lease from the fuel companies.  So now if your ever short on oil and you want a few 20 litre                                                                                  containers filled up, call in.

 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 Diameter 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.

Outdoor bath heating coil 415mm od coil to fit inside a 44 gallon drum. 15 metres x 12.7mm.

It's upside side down currently. The drums on feet, the top exits the bottom of the drum for the cold inlet. 

A woodfire setup inside the coils, to get boiling water.

A small water pump maybe required.


This customer contacted us, to see if we could build a waste oil burner blower heater unit for her Jacketed water heater, she had limited space, a diesel burner like the one above, was heating the boiler, it was going to cost thousands of dollars to replace.

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

Just free waste oil or used oil is the correct term.

A Ryco oil filter/water trap, has been fitted to reduce the ash buildup in the pot and to remove any water in the oil.

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 customers with these diesel burners are not only burning diesel, but burning out a lot of compressors too. 

Best to date 5 air compressors. Our burner blower units start to look a very cheap option.

She, heats the 180 litres of water, to 85c, in two hours,which is enough for the households needs for a day. This is also feeding radiators and showers.

The temperature of the heater is controlled via the timer, which controls the amount of oil entering the burner, this keeps the heater at a set temp so there's no fluctuation in the fire so it can't  get out of control. So each dose of oil is burnt up before the next dose is delivered to the fire.

The walls of the heater would only ever get to 85c, and if the flame ever did go out, the slight drop in temperature would be picked up by the thermostat, which in turn will turn off the fire and oil supply.

                                                                           Thank you Kay for the image.

Above the waste oil controller uint in action dosing 1 second of oil every 6 seconds in this case. The oil is pretty much all burn before the next lot arrive so there's no build up of oil in the pot. Note the water temp 82c.

We have developed this waste oil controller unit, because the simple fact is when oil warms or gets hot, the viscosity rate changes to twice the flow rate from cold oil. A Lot of guys on youtube haven't worked this out, because they still use taps. Extremely  Dangerous.

So whether the oil is cold or hot the pump, pumps the same amount. The other reason why, is if the fire ever stopped, the thermostat turns the oil pump off at 30c. This saves waking up in the morning to a 205 litre oil slick on your pool or your yard covered in 1/4 inch of waste oil.

 I couldn't think of anything worse.

The 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.

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

Sending heavy 45 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 alot cheaper. Great for warming up the entertaining area and for heating Radiators, pools etc.


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

We need to know the width of your firebox so we can weld the fixing plate. 

                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 needs to be 55mm square, the fixing steel plate will cover any gaps.  

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.

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 hours, depending on the oil your burning.

Another waste oil blower burner converted logfire.

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.

We understand this is heating a spa pool at an amazing rate. 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 almost boiling in an hour. 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 already have, to heat 8 radiators, 2 showers, spa pool, etc, take any logfire with a wetback, it would need to be connected to a 280 litre second hand hot water cylinder, the log-fire would heat the water to 90 c 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 radiators. I would think four radiators in each circuit. The only thing is radiator water can become dirty with a little rust so you may need a filter to remove this if heating a spa.

This heater was 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.

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 they are dangerous, as they can't be controlled.

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 1-2 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, cutting out the fire and stopping any oil spills. 

You should always have your heater sitting in a cut down 44 gallon drum capable in holding the same amount of oil as your storage tank ideally 20 litres if your still using gravity system.

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

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.

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.


Timer pump delivery system.

Not shown is the tubing and fitting to connect up the oil.



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.

Kiwi's, please contact us regarding payment, if you don't use PayPal.

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.

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 Jim, 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 "one second pump, 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 handyBUY 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.

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 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.

This heater has been fed too much oil, showing the chernobyl effect.
