You have done a great job of it Leo. It's different to mine in that you have a lot bigger primary air hole in the pan and far more heat being generated there as a result. In my heater the main heat is in the secondary burner tube and above and as a result probably get more ash than you do.

Ahh, it's good to see the spirit of the home tinkerer producing real results!

@lookoutleo A great job.

Keep the faith my Scottish brother !

@ozzirt hi there

Are you still using this with waste oil? How does/did it perform?

Hi leo do you have problems with the ray burn sooting up???

Can you run copper pipes from these?
