What Our Customers Are Saying....

A local energy company came and did a study on my building. Because of using a waste-oil burner, their estimates suggested that I saved over $100,000.00 in heating costs over a 12-year period. Since using a King-Built burner, the maintenance on the burner has been a piece of cake compared to their competitors. Since I've installed a King-Built burner, I know for a fact that I use less oil each year.

About KingBuilt

Over 7 years ago, one of the present owners and lead engineer of, Inc. was evaluating a popular “used oil” boiler that he had purchased, attempting to find a way to make it more reliable and require less maintenfance. The problems he identified were oil carbonization in the burner, and the related issues caused by this grit. As it turned out, these problems were not only present on that unit, but were actually inherent to the technology being applied to all systems available at that time. What he came up with was a combustion system different from all others, with unique features that not only solved these problems, but now enables the systems to burn a multitude of oils, without the concerns and limitations the other systems share.
