These are some very simple way that you can do for DIY waste oil heater. This will run on anything from engine oil to vegetables, transmission fluid, Hydrulic and other oils. You can heat up some animal fat or lard, and they will be very happy with that too.
The key idea of DIY waste oil heater is the burner air / oil feed tube. It’s just a little out of the exhaust pipe with a 90-degree curve and eventually become the boards on the side air exit is not straight. You can test the design plate without the proliferation and it has been successful. However, the startup is more difficult and more difficult a lot of oil on the stove when the feed control of production.
You need to use high oil gravity from a container fitted with a gate valve on the drum to control the flow of oil. This oil is distilled at the end of the air inlet tube and was blown away on the stove all through the incoming air from the blower. There is no nozzle, pump or something else running out of oil just a little passage. Because of the control valves in the fuel flow, there is no fuel consumption anyway. That’s all about DIY waste oil heater.
