(B20) Blend Bioheat - A Better Energy Source

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. We are proud to deliver a better energy source to our customers and our community. No decision on your part is required.

We will provide (B20) Blend Bioheat to all of our customers this heating season based on availability and our ability to deliver it at no additional cost compared to conventional heating oil.
