Bioheat is an exciting new heating fuel that blends standard heating oil with renewable biodiesel - resulting in a safe, exceptionally clean, and environmentally friendly fuel. Bioheat comes from our usual reliable supply of heating oil and agricultural products, many produced right here in the USA.

One of Bioheat's many great benefits is that it can be used in any oil heating system without modification. As our customer, you will continue to enjoy the same seamless, reliable heating that you have come to expect from Leahy's Fuels.
