How Connecticut Oilheat, aka Bioheat® Fuel, Benefits You

Connecticut's energy markets are abuzz with a word you might've heard recently: Bioheat. It sounds like something new -- but, the fact is, this reliable, affordable, and renewable fuel has been helping Connecticut's home and business owners meet their heating needs for years now. It doesn't matter if you're in Waterbury or Danbury, New Haven or Norwalk, Bridgeport or Hartford. In Connecticut all oil heat is Bioheat fuel.

Bioheat fuel is defined as a blend of biodiesel and ultra-low sulfur heating oil. This blend is measurably safer and better for the environment than conventional ultra-low sulfur heating oil, because biodiesel comes from natural, recycled resources like soybean oil or used restaurant grease.

According to a study by the University of Connecticut, ultra-low sulfur heating oil in Connecticut contains an average of 7% biodiesel. That means the stuff inside your oil storage tank right now is some of the cleanest, greenest heating fuel in the whole country!

Green is great, but what exactly does this mean for you and your neighbors? It all goes back to Bioheat fuel's three core benefits: reliability, affordability and renewability.
