Blue Flame Heater.

The latest blue flame Heaters we have 2 instock most welcome to collect $890.00.

It's on YouTube going. 

Both have sold sorry more to build.

The lastest blue flame heater.

Testing began on this heater it being used to heat water.

What started this quest, to use waste cooking oil as a heat source, this all started when i was working at a bakery, and every month an oil truck would pull up, to take away the canola oil that was used in the vats for cooking donuts, chips, meatballs, which sat in drums, out the back of the shop. 

I asked the driver what they were doing with it, he said make soap, yeah right, I thought.

So, i took some home and lit it, I had about a litre of oil it burnt for over two hours, i was amazed, but it smoked badly. 

That didn't matter i had a great free heat potential.

The next year was involved in cleaning the smoke up.

We built the 3-legged moon launchers, to the blow in the pot type heaters, and now the blue flame heaters. 

The goal was to heat my house for free which has happened quite quickly as many other homes, pools, spa, workshops, hothouses and business around the world. 

Now we build the blue flame heaters which are the best ever, they never smoke, controlled with a waste oil controller.

If you have the blow in the pot heater, we can change them over to the latest blue flame heater.

The cost for this is $790.00 nzd

Contact us to deliver a heater to your work.

We are had issues with our freight company PBT and have closed the account. Overcharging.

We now run the heaters to Palmerston North or Taupo at a cost of $100 for fuel. We can arrange a time and place to meet for the swap. 

With the cost of heating has skyrocted, more people are looking for ways to limit the amount energy they use. 

  Have you ever looked at waste oil? Its free and now burns super clean, thanks to the blue heaters we build.

Heat your home for free this year & every year with a blue flame waste oil heater, these heaters never smoke, fairly quiet, and after the purchase of the heater, the rest is free. It can be setup outside heating a radiator in the home 1 large radiator heats the top level of our home to 23-24c. 

That's a large lounge two bedrooms two toilets and a hallway. 

Most welcome to come & view this setup, to see if it suits you home, please email us to arrange a time.

we are in Havelock North, Hawkes Bay NZ.

The blue flame technology for the waste oil heating industry is here now. 

We've made quite a few designs over the years, but we have found these blue flame waste oil heaters, the best. Why, well, the main reason is they have extremely low NOx emissions and burns the water that's present in your oil. Just a better stable burner.

The important thing to remember is that blue flame technology remains highly efficient with the added benefit of significantly lower levels of NOx emissions, adhering to current emissions limits and anticipating forthcoming lower emissions targets expected in 2022.

Benefits are with their ultra-low NOx emissions levels; blue flame oil-fired boilers are a greener alternative to traditional yellow flamed oil-fired boiler models.

Blue flame burners guarantee superior efficiency and ultra-low NOx emissions (57mg/kWh)

The heat output is incredible.

The vortex 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 smoke from time to time, but these don't smoke because the vortex of the flame. Another thing we don't filter our oil it burns everything including water in the oil. 

If you have a business which services cars, trucks, tractors or machinery, you already have a source of waste oil which maybe you pay dearly to recycle. That oil could be heating the workshop for free, improve moral in the workspace, and improve production. 

Don't think your workshop is too big. We heat aircraft hangers, mechanics workshops 

engineering, and tractor workshops.

Why pay someone to remove your waste oil just to turn around and buy natural gas, electricity, or propane to heat your building? 

it cost your business good money to have it recycled and we question recycled. 

Used oil contains valuable energy that can be used to produce the heat necessary to keep your facility comfortable and productive.


There are many questions on burning waste oil as a heat source, interesting angle for us.

My understanding is that the UK regulator (Env. Agency boooo) lost a case in the high court, which ruled that use of the oil in question to HEAT gave it a purpose and it was no longer a Waste product 



Available in New Zealand

The plans are $50.00 nzd you will have to email us to go ahead with these.

Some Americans are saying they are saving over $20,000 usd in propane, with the blue flame heater.

If you've looking for an alternative form of free heating, to heat your home, workshop, farm shed, pool, or hot

water cylinder.

Apart from the initial cost of setup, like any heater, or fire, the heating part is totally free, unlike 100% of heating systems that costs dearly. 

Our heaters are a commercial type of heater, they heat large areas great to heat a home with radiators with the heater setup outside or spa & swimming pools. 

  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 $135.00 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.

This heater we tested it yesterday and was surprised at how clean it was, it looks like we are burning meths not waste oil. 

This video was filmed at night to show all the blue flame which you don't see in the day. 

Theses heaters above are available at $1250.00 plus freight, they come complete with round 3mm thick lid, and flue housing, and waste oil controller, and power supply. The test temperature was to 400c.

Email us with your order [email protected]

If water heating is what your after then 1x 15 metre copper coil is worth $350.00 fitted, to be added to the heater price.

#Currently we have these two 45kg heaters instock.

The top heater is the blue flame type 45 kg cylinder that will heat large areas 

and is priced at $1250.00 or near offer. We will put a 15 meter copper coil in it for this price or deduct $250.00 if using just the heater.

The second blue flame heater on the trolley 1/2 45kg cylinder still will 

heat fairly large workshops complete with waste oil controller and 20 litres of waste oil. 

Priced at Sold Sorry.

We can only sell these to New Zealanders. If you are interested in this email me to organize a viewing or purchase.

They're designed to be installed outside, heating water, heat the home, pools, radiators, hot water cylinders,

dairy sheds, glass houses, chicken sheds, brewing, and underfloor heating.

We have supplied a lot 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.

All overseas customers use PayPal for buying from this website. 

We don't ship complete heaters out of NZ the freight kills it. The last one we sent they quoted 2000.00 the account came $3500 but i must say it was there by the end of the week which was amazing.

We find it the safest way to purchase online.

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

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.

 I've been using our home blue flame heater for the 3 months 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 cardboard, turn on the oil, then the fan, away she goes. Gets 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 23c - 24c. The heater never alters, never smokes so now I've taken the flue off it which hasn't effect it, no soot anywhere, it's brilliant, it runs like a gas heater so stable.

And turning off is quite a quick, turn off oil, the flame quickly extinguish turn fan off 5 minutes later.

Ash I use the vacuum cleaner to suck it out.

Plumbing up a copper coil to a closed loop like a radiator.

There are a few things you need to know.

Use copper plumbing, expensive but well worth the extra money. 

Off the copper coil at the hot side or the top of the coil, in your piping you add to the coil you'll need to put a T to an open vent, this is just a 15mm copper pipe going up to the house spouting where the excess steam and water pressure can exit the system. 

On the cold side of the coil, another T fitted for an ajax valve will be fitted, this is so when the pressure in the system is released to the spouting the loop requires automatically filling and the Ajax valve does this.

You will need to connect the ajax valve to a garden hose and set the ajax pressure by turning the tap on only 1/4 turn then adjusting the pressure with the ring on the ajax valve so the water comes out the open vent, then turn the ring a full turn back so no water exit the vent.

This may need adjusting once the fire is going and the water is heating.

A circulating water pump on the cold side of the coil is a good option too, it stops banging in the pipes at startup with thermosyphon. 

Without this, it would be a potential bomb, and you would blow radiators time and time again.

Connecting to a spa pool.

This is an open loop so the above doesn't apply.

Cold pipe out hot pipe in.

A circulating pump would help too.

Be very safe with hot water.


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 is currently in stock give us a call or email us New Zealand only. Thanks

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 all the 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.  

We are testing this heater today again, but with a copper coil fitted, we need to find out the water heating ability. 

We will post here later today.

 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 they 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. 

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.

 Testing of other types of burners.

This is our old heater that heats the home has been upgraded 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.

 Copper coil to heat an outside bathtub, or the coils could be double to heat a spa pool. We have it for sale at $199.00 NZD.

$350.00 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.

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.

It's been difficult to source 45 kg cylinders at times, and more so now with half the freight companies, with driver with no dangerous goods license it making the very limited and very expensive to freight.

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.

Timer pump delivery system.

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

For custom built units please email: [email protected]

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.
