Great passive design.

A small proportion of it burns in the pan and the airflow from six downward facing inlets blows the flames across the surface of the oil. Most of the resulting hot vapour rises and is mixed violently with air entering the secondary burner tube maintaining the main flame.

that looks great would love the plans if possible to make one of them

That thing is awsome !

@glumpy10 I'd be very interested to hear how it goes with a water heater.

This is the kind of heater i've been trying to find plans to build for ages. Could you send plans for it. Many thanks

Hi ozzirt, awesome looking heater. I looked for the URL link to the plans/drawings that you mentioned, but couldn't find them. I would really appreciate a link to them. Thanks, and keep up the good work.

So does that secondary burner protrude down into the camp oven so that the base of it is about 4" above the surface of the burning/vaporizing oil then?

any chance that you could also send to me drawings for the burner for veg oil.

How many inches is the burner spout with the lower hole?

Does most of the oil vapor burn in the pan, or does it continue to burn further up in the heat exchanger?

@amgalanbator I'm sorry, but I do not sell my heaters, however there is a drawing that would help you if you wish to build one yourself, the URL is shown in the first comment.

Hi there i am making a oil drip heater somewhat like yours but i cant find brake drums that are big so i got a used electric boiler do you think it will work ok

Do you think a mini version will work?

Hi spike.. could you please send me some plans I have built 1 for my rayburn and having soot issues.. how big does secondary burner have to be 6" wide by how tall? Can the chimney have any bends in?? How tall chimney taller the better or not??
