Does Bioheat® give off as much heat as regular heating oil?
The energy content of biodiesel is similar to the energy content of heating oil so a blend of biodiesel and heating oil will burn the same and give off the same heat as regular heating oil. For those of you into details, according to a study done at Brookhaven National Labs, biodiesel has a heating value of about 133,000 BTUs/gallon, compared to 138,600 BTUs/gallon for #2 heating oil. So a B20 blend would contain 137,480 BTUs/gallon. Biodiesel burns more completely than regular heating oil, which means your furnace will operate more efficiently.
