NORA releases Biodiesel Blends Quick Guide for technicians

As the liquid-heating industry continues to decarbonize through ever-increasing blends of biodiesel in the fuel, questions have arisen as to the proper way to manage service in the field.

The National Oilheat Research Alliance consulted service technicians, educators, manufacturers and its own research to identify the most common questions about servicing biofuel-powered heating appliances.

The results were narrowed down to six questions centered around cad-cell readings and shut-down, head coking, setting up a combustion analyzer, fuel-unit (pump) binding, filter clogging and carbon-emission reductions.

In response, NORA has issued its Biodiesel Blends Quick Guide, in which each of these is addressed in a simple and actionable manner.

“Technicians are seeing more and more biodiesel-blend installations, which have raised questions and, unfortunately, have often generated misinformed answers,” said Bob O’Brien, NORA’s director of education.

“This quick guide gives them the simple and correct information to make sure the system continues to run safely, reliably and efficiently,” O’Brien continued.

The quick guide is available online at

NORA was authorized by Congress in 2000 to generate funding from within the industry, allowing the liquid-fuel industry to provide more efficient and reliable heat and hot water to American consumers.

NORA’s efforts focus on energy efficiency, environmental responsibility, safety, research and development, and professional education, with particular emphasis on transitioning heating oil and its appliances to a low-carbon source of heat and hot water.
