Hi All,

Does anyone have (or know of online) plans/designs for a decent waste-oil heater please?

I need to heat quite a large space at work, prob equivalent of 3 double garages and I think I can get holdof some waste oil, so would like tp make a waste oil.burner...

Would love It If I could build it with scrap-type parts so its as cheap as poss!

As always, thanks in advance for help and advice...

Steve

I found this last year...waste oil heater
I might have the file downloaded at work. I'll look tommorow.

The one I am going to have a go at building in the next few weeks (or at my current rate of garage time, months) is this:

It is slightly different from the Mother Earth burner and better than that Roger Sanders jobbie too from what I've read.

The main different is that it sort of burns the oil twice (read his website for a better explanation).

He doesn't charge for the plans, you can email him and he's got links here and there to other guys who've built other drip style burners that have been quite smokey then buitl one of his and its burnt virtually clear.

He lives in Oz but has told me of a guy who has built a big one in a workshop in Daventry (just down the road from me).

I'm going to go and check it out next week hopefully.

I'll post a thread back on here when I have something decent to report.

Search on youtube for "spike burner" or "spike heater" (he's called Spike - it doesn't use a spike in the design!) for a few vids, his username is something like ozzirt.

If anyone else goes this route let me know and we can compare notes.

Mine will be fairly small ~4" secondary burn tube and flue as I only have a double garage to heat.

That said I may run a coil of water in it or around the flue and send excess heat into the house via a heater matrix or similar (as inspired by Matt's dad Ivan (Procomp)).

I strongly advise against ---- burning waste oil in heater poses a very real danger of an explosion.

Can you elaborate on that?

I agree if its goes petrol or other volatiles in it from either pouring in "waste" petrol or cars that have been running very rich I can see a fire risk but I´m not sure it would explode?

The gent who came up with the design I am thinking of using has used it inside his house for well over 10 years without issue.

I'm refusing to work on them now (commercial and industrial not home made jobbies).

Waste oil heaters are a nightmare, they're usually a standard cabinet heater with a modified burner such as a Kroll.

Need to speak to you on the weekend anyway, explain more then, you love egg

Read the description of the first test run, I have read about these burners getting into a cycle where they burn out of control as he explains. It's to do with the oil feed altering as the oil warms up and thins so it delivers more to the burner.

surely this can be overcome with a simple valve possible even a thermostatic one

In the design I refer to the oil feed pipe does not run around the flue or similar, the preheat of the oil is done within the primary burner by it running down a piece of angle iron before it drips on to the pan. Ok so a bit of heat may soak into the copper pipe where it enters the burner but nothing like the amount of heat you get when you wrap the copper oil feed pipe around the flue. This also apparently leads to oil getting baked on the inside of the pipe if it gets to hot - not a problem in this design.
