Waste Oil Heater Forum - Your definitive source for burning waste oil for heat.

Great. I have a yearly suply of about 200 litres of used oils(motor, hydraulic and gear oil). i´m from Spain, so all the chit-chat about brands is like alien talk for me. Maybe you´ve heard of "Roca", it´s the brand of heater I have. What do you mean when you say type of burner? I know it has a nozzle which delivers fuel like an injector. Basically, it´s a gas water heater that uses diesel from what I see and all the water is recycled with a small water pump. The plumbing uses 1,3 bars if that has something to do with anything. I was told that if I changed the nozzle I could burn biodiesel(due to the thickness and impurities the nozzle has to be wider) but I am wondering if I could burn oil instead. The winters where I live are not so cold, like it´s unusual to go below 32ºF (0ºC) so I think that the fluidity would be quite good. I am looking to understand the basics of what you guys do. I ain´t got no engineering degree, I have only some basic mechanic understanding, but I am a fast learner under good guidance, and it seems that you guys know what are doing. I´ve seen photos of such elaborate installations on here, so I am really impressed, but I was thinking of going more basic level if you know what I mean.  Anyway, thanks for the answers and I hope to hear from you soon.

Greetings to all. Came upon you guys by searching for a way to make bio-diesel for my diesel heating system at home and thought that using used motor oil is a interesting idea. I´ll be lookin around for inspiration until being able to fully understand the way these things work. At an early glance is quite simple but it has it´s downpoints. I´m just fed up with the rise of gas/diesel prices and looking for a way to try to go by it easier. Hope you understand what I mean. Thanks for reading this. Hope I´ll have a good experience here. Time to browse around the topics. Cheers!
