Can Biodiesel be safely used in fuel-oil furnaces?

Question

I just got a new fuel-oil furnace and was looking into making my own biodiesel, but wanted to check if it could safely be used in my home heating furnace as well, before making a decission. We live in Wisconsin, and are concerned about the risk of the biodiesel gelling up, anyone know anything about this?

Answer 1

Biodiesel is notorious for gelling up,but with additive,it should work.There are websites that sell skids to make our own biodiesel.

Answer 2

first off....diesel is the bottom of the gas/oils line. Gas is top, then kerosene, stove oil, etc. then diesel is the least refined. Probably if you put in additive, bio-diesel might work. Diesel engines run on compression...(no spark) The others (including your furnace ) use spark to ignite the fuel at the burner. Bio might bung up your flow nozzle in your furnace. Check with a burner serviceman. Also, if you're gonna make your own, keep it where it won't gel up
