“Bio-diesel fuel used in oil tank.” Direct quote from an RMLS listing. Not one I had come across before. My first skeptical reaction was that it was Realtor-speak for “Time bomb in basement.” That is not the case. SeQuential Biofuels brings us the following from their website:

Low biodiesel blends such as b20 are the equivalent to petroleum diesel in standard home heating oil furnaces and commercial boilers. With attention to the appropriate precautions, pure biodiesel (b100) can be used in heating oil furnaces and boilers as well. SeQuential distributors can deliver pure biodiesel or biodiesel blends in bulk containers (55-gallon drums or 275 gallons totes) or can deliver biodiesel fuel directly into your bulk heating oil tank.

Does anybody have any direct personal experience with biodiesel as a heat source?
