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

Greetings , thought you guys might be interested in a waste oil spa pool heater, we going to hook it up tomorrow , has a 4 inch inlet pipe and a six inch chimney stack , burner is an aluminum v shaped dish on a central plinth , main body of the heater was an off cut of a spiral welded pipe , the water will be heated in a 32mm stainless steel tube which is looped around several times  inside, was running this setup in an old metal drum using wood as a heat source , would take about 4 hours to heat from cold to 40 celsius , the old drum rusted out and after successfully building a waste oil heater for the shed thought id try and make a spa pool heater, will add some pics ,
Regards
