Guardian Fuel & Energy Systems

Family Owned and Operated Since 1993

When we started our family business 20 years ago, we knew that we wanted Guardian Fuel to provide a better customer experience for home heating than you could get anywhere. We also knew that someday, people would demand renewable fuels for home heating, because there are better ways to power our planet than petroleum!

We know a good thing when we see it! BIOHEAT® heating oil, a blend of biodiesel and traditional heating oil, became available to us in 2006.  Biodiesel, a natural renewable fuel is not only biodegradable, it blends well with petroleum fuels for many uses.  It actually improves petroleum's response in your heating system!

BIOHEAT® fuel blend replaces conventional heating oil without any conversions or retrofitting to your system, so you don't have to worry about making an investment to get the best heating fuel available today.

See how good it feels when you do the right thing.  Join the evolution of oilheat.
