Waste Cooking Oil Burner ( Re-edited ): For almost free heating 

Just came across your video, and I agree 100%. I designed a burner to run in my converted wood stove, and I have been running it now for 6 years. It will heat my 800 square foot shop with no problem. If I crank up the oil dial, the stove can reach 1200 degrees fahrenheit if you turn the shop lights off, the stove is red, which means it's HOT! I have a good supply of used oil, which I filter. The bottom line is that it's cheap to run and gives off a lot of heat!😊

Wonderful information, very useful, thank you for posting
