A new study shows that a 20 percent biodiesel blend is fine for home heating use. The National Oilheat Research Alliance (NORA) says they tested blends of ASTM D6751 biodiesel with both standard and low sulfur heating oil and found that the 20 percent blend can be used in heating oil without incident.

Field experience with Bioheat® fuel (blended heating oil and biodiesel) has been overwhelmingly positive. A recent service organization survey conducted by NORA and Brookhaven National Laboratory observed that some 35,000 buildings are currently using Bioheat® containing more than 5% biodiesel with no issues…

Winter operability is essential in serving oilheat’s customers. Biodiesel blends can have a significant impact as the feedstock affects its winter characteristics. Wholesale suppliers and retail marketers need to be sure the product they sell is right for the temperatures at which it will be stored at and used. An outside tank in Maine may need a different product than an indoor tank.

NORA says it has been working with the National Biodiesel Board and the oil heating industry state leadership groups to make sure biodiesel used in home heating oil is of the highest quality to eliminate any issues, especially during the coldest weather when homes need to be heated most.
