Rock Energy Systems LLC is a Wisconsin-based manufacturer focused on space heating equipment. The company owns three brands—Clean Burn, Lanair, and SunFire—that provide portable radiant heaters, waste-oil furnaces, and boilers. Their systems generate heat by burning used motor oils and other petroleum-based fluids commonly used in engines, with production centered in Janesville.

The business serves customers seeking heating solutions that can utilize waste oil as fuel, embedding itself in a niche within the machinery manufacturing sector. In August 2023, Rock Energy Systems expanded through the acquisition of Northwoods Energy LLC.
