Althought drip fed waste oil heating is still our name we are far from than that with fan forced airflow 

with electronics to control the heater.

     Thank you for another excellent year of Waste oil heating, I hope you have worked this heating out, and are enjoying all the free heat these create.

Happy New Year to all from Drip Fed.

We are here to help, if you've built your own heater, and having issues of overheating or smoking please get intouch.

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

PLANS for the 45kg Heater.

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

                                                                           We the seller get no information of yours from Paypal.

We have changed our minds on the 9kg burner going under inside the 45kg cylinder because it's a hassle to get the cylinder between the legs so we have gone with the above burner unit instead. I think this will work a treat. At this stage the blower burner has been fitted and the pipe for the pot has clips fitted on the sides, so it attaches to the bottom of the 45kg cylinder, similar to a light fitting. It can be removed easy incase of ash build up. I've fitted handles to  the sides of the pot to make it easier to remove should it require cleaning.

                               Currently adding another copper coil into an existing pool heater to speed the heating process up

                                                                             It'll end up with 30 metres of copper tubing. 

                                   We are supplying a circulation pressure pump with this, which will increase water flow 10 fold.

                                        1/10/2020 Have it the stage of being ready to have the coils fitted, once they come into stock.

Another spa pool heater under construction however will end up waiting for this coil too.

Have built the larger heater with the above burner in the video above. Have yet to light it at re-test it in a 45kg cylinder.

I'm kind of hoping it turns the whole cylinder red with ease as a heater, as no coils have been fitted.

Reasons why we think you should look at our burner blower units, rather than a waste oil or diesel blower burner unit.

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

Our units use a fan, not a compressor for airflow, and I understand these burn out air compressors.

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

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

They come with huge power accounts to pay at the end of the month, ours don't get a power account.

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

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.

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

                                                           Issues with burning waste oil.

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

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

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

Finally they are being burnt for energy recovery.

We have an issues regarding controls in place regarding burning of waste oil for heat recovery, even when burning it cleanly, and who is, and who isn't, allowed to burn it, and the way in which they are allowed to burn it. If your in a residential area you are not allowed to burn waste oil unless you look into used oil or heating oil, but if you have an orchard over the fence from you,  all good mate, they are allowed to burn it for "frost protection", and can be burn it anyway they see fit, even in an open 44 gallon drum or their dirty smelly smudge pots, so this makes you think, the issue isn't the emissions or the dangerous chemicals released into the atmosphere, or even the awful smell from the smoke.

They burn waste oil everywhere in the world, come on councils it's time to tidy this up.

 With more and more oil to be stocked up in rusting 44 gallon containers, I know for a fact people will just pour it back into the hole in the ground or drains, or water ways to get rid of it and there are people out there that just don't care.

We are far better burning this stuff to remove it before it starts damaging our waterways, rivers, and sea from becoming another hazard.

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

Ok, you say this is adding to global warming, my augment is this type of heating doesn't involve cutting down oxygen producing trees to heat our homes. etc  we are leaving them to grow to remove the Co2 from the air. I resonantly flew over the North Island of New Zealand it is covered in pine trees.

I get annoyed when Councils say that these chemicals entering the atmosphere is highly poisonous when you know that's not so. 

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

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

We just found this write up regarding waste oil heating.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Burning waste oil, the thick black choking smoke has been reduced to nil, and now in 2020 is a extremely efficient clean burning free fuel straight from the 44 gallon drum, as in the video above shows, and capable in heating almost any area you put the heater into.

Cleaner burning than today's new wood fires.

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

And the best IT'S FREE.

YES FREE HEATING.

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.

USE A PLUMBER 

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.

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

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

These heaters in these videos have since been painted black
