I saw a posting in a biodiesel forum about a waste oil heater at

Has anyone built this thing?

Either you have no idea what you are talking about or you work for one of the waste oil heating manufacturers.

Did you read the forum about this thing? It doesn't smoke at all.

In addition, the "proper" waste oil burners cost $5000 or more and then you have to pay hundreds more every year for that servicing you are talking about.

I have an ample supply of vegetable oil and I've been told that manufactured waste oil burners WILL NOT BURN VEGETABLE OIL.

In addition, I've seen the expensive waste oil heaters and they do smoke a little bit in between breaking down and plugging up and filter changes.. oh.. and inbetween those expensive service calls.

How does it feel to spend $200 for a service call to replace a $2 part you could have done yourself?

(what a rip off)

Global Warming - Not possible when burning waste veg oil.

So I guess I would like to know why someone with no clue would bother to respond to a question when they have no idea what they are talking about.

I was slightly put off because i've built other waste oil heaters.

Most manufactures of waste oil heaters have done nothing but copy the good old fuel oil furnace gun.

How many of your waste oil burners will ignite half wet vegetable oil? None I bet.

I'm not the put off sales-person. But I have enough experience in building things to know that you're trying to invoke fear to keep your sales.

You can always spot a con game when people start quoting laws in the way you have.

Nice try but I think people can read between the lines.

In addition, I asked if anyone had built one. If I wanted some service guys completly biased opinion, I would have gone and visited a waste oil manufactures site.

I think I'm going to build this thing.. The fact that some manufactures service representative is so against it tells me its probably a good deal.

Thanks for the tip.

Now your using the word "explosive".

Maybe your burners are explosive.. I built one years back based on a water heater.. It is not possible to make it explode. I tried.

I tried heating it up and filling it with oil vapor and then igniting it.

Wow.. Nothing happened! Hmm.. seems oil has a high enough flash point to make it NOT want to explode.

In fact, oil is NOT EXPLOSIVE. Please find me one referece to oil being explosive.

I think what you mean is that your style of commerical waste oil heater can create conditions compatable with creating an explosion with your heater.. For this reason, it should only be serviced by a certified person.

Sounds like a design flaw to me.

The only way to get the waste oil heater I built long ago to explode is to fill it with gasoline.

Change tactics. Fear mongering doesnt work that well anymore.

But that was funny.. EXPLOSIVE! Danger Will Robinson!!! Danger!

having had a home made waste oil heater operating in my house for 11 winters (nearly 12), all i can say is that most of the warnings i have read here are at least highly overstated and at worst a deliberate attempt at scare tactics.

No smoke no smell, never had a complaint, and my nearest neighbour is 20 feet away downwind.

There is no need. Having been a merchant seaman for all but the last two years i was always away, and my wife and family never had the slightest difficulty in either running or maintaining the heater.

Maybe in the USA people are becoming lazy or useless, but here in AUSTRALIA, people use their common sense. Any person that could light and maintain an open fire would have no difficulty in doing the same with my heater.

Slide out the burner pan.

Clean it if needed (Empty the ash)

Put a firelighter cube or splash of kerosene in the pan.

Place the pan back in the heater.

Light it through the air hole.

Adjust the oil flow to minimum.

Allow 10 minutes to get up to working temperature.

Set oil flow to attain desired temperature.

When finished turn off the oil.

Hardly rocket science, by any stretch of the imagination.

My wife lit it only an hour ago,... for about the thousandth time. No screams, no dramas.

Your answer is typical of someone with a vested interest that has been backed into a corner. I'm sorry, but I refuse to take part in the "dumbing down" of the general population.

With attitudes such as this, no one would be game to change a light bulb. Handymen and people willing to help not only themselves but also others would be non existent.

Remember,... "Most of the worlds major improvements were not made by engineers, they were made by some lazy slob who wanted to find a simpler, easier or cheaper way of getting something done"

I'll guarantee that in the last 12 years, I've had less maintenance problems and less expense with my heating system than just about anyone you can name.

Original expenditure less than $2000 most of which involved tanks and plumbing.

Annual costs less than $30 for fuel collection costs. This includes all vehicle running costs.

Waste: approximately 130lbs of ash p.a. Cost of approved disposal $4 p.a.

The "danger" involved, is probably about equal to that of having an open fire in your home, the cost efficiency of which is far worse, and the work involved is much greater.

So,.. I would be more than a little suspicious of your motives if the local supermarket representative tried to tell other readers my home grown vegetables were dangerous because that food did not go through the treatment given to commercial crops.

There is a vast moral difference between giving advice with a genuine concern for the safety of others, and merely protecting one's own self interest.

There are already more than 12 of my heaters either in use, or being manufactured in the US, five of which are in Alaska, 1 maybe 2 in upper NY State 1 each in Wisconsin, Montana, Nevada and others where I'm not sure of their location. there are two in commercial premises in UK, 6 in Australia with 3 in the process of manufacture and two in New Zealand. One unit in Western Australia is heating the lap pool of a quadriplegic gentleman, and also heating the floors in part of his house.

If you care to look You will notice an unsolicited "plug" for my heaters on YouTube. This owner has his fitted in a Government Department owned house. He also has a short video of it running.

Of course, I suppose it never occurred to you that perhaps I'm making no money from it, because I give away my drawings and any help needed free of charge? It was never intended to be a money making proposition. But seeing so many people have asked about it, I am quite willing to help them. I estimate that about one heater is actually built for every ten enquiries. Or that is about the number from which I receive continuing contact and often photos and/or movies.

Oh how comforting it must be to revel in your own ignorance. I have had two approaches from companies to manufacture this heater in various configurations. One is in England and is a company who normally manufactures 10 - 50 HP Diesel boat engines, the other is an offshoot of a German company in Brazil that normally manufactures components for the die casting industry.

I'm sure that the first is worried because I can not guarantee them sole manufacturing rights for UK (that was a point of contention). They may be trying to register the design themselves, as I have told them I was not interested. The South Americans are hastening slowly. At the moment, the principal of the company is in USA negotiating with a well known small engine manufacturer on his core business.

Attached below you will see a "proof of concept" heater thrown together by the British company about ten months ago. Seen her undergoing its first test burn in the doorway of their workshop. Yes, that's snow on the ground. This test unit was used in that machine shop all last northern winter, (other photos are available of it in use)

You see, the world is a very big place and there are many places outside of the USA where people have a little more freedom, flair and imagination.
