Bioheat is a blend of heating oil American Society for Testing and Materials (ASTM) D-396 and biodiesel ASTM D6751. Biodiesel is a nontoxic, biodegradable, domestic, renewable fuel derived from natural vegetable and animal oils. The U.S. Environmental Protection Agency (EPA) recently confirmed biodiesel as an “advanced biofuel” that meets the demands of the EPA's Renewable Fuel Standard. It enjoys the highest energy balance of any renewable fuel. For every unit of energy used to produce biodiesel, you get 5.54 units of energy back. The vegetable oils and animal fats used for biodiesel feedstocks are not produced specifically for biodiesel; they are a minor by-product of food production. So, they do not suffer from the fuel-from-food stigma the ethanol does. This chapter covers the properties of Bioheat and the blending, service, and maintenance protocols required to ensure that Bioheat is a safe, reliable alternative to heating oil. |
