Rock Energy Systems, LLC, based in Janesville, Wis., has acquired its largest competitor, Nashville, Tenn.-based EnergyLogic LLC, to create the nation’s largest manufacturer and distributor of products in the waste oil space heater market. Rock Energy Systems will continue to operate EnergyLogic’s Nashville-area manufacturing and distribution facility at 5901 Crossings Blvd in Antioch, TN.

Waste oil heaters, which both companies manufacture, allow automotive repair and maintenance shops to heat their space by burning the oil drained from vehicles in an oil change. The genius of the technology is that, rather than paying to dispose of waste oil, it is turned into an asset that saves on energy bills.

EnergyLogic was founded by Rob Stevens in 2001 when he purchased the Black Gold waste oil heater company and rebranded it as EnergyLogic. Stevens later purchased the Firelake waste-oil  heater company and expanded the company’s reach by adding VAL6 portable radiant heaters and MacroAir high-volume low-speed (HVLS) fans to its product line. Since 2001, the company has grown its market share from 6 percent to over 30 percent, distributing waste oil heaters and fans throughout North America, as well as in Russia, Japan and several other countries. Its distribution partners include a network of independent dealers as well as national partners such as NAPA, CARQUEST, Advance Auto, O’Reilly’s and AutoZone

“We are excited about the opportunity to add EnergyLogic and its multiple brands to our family of brands to create a company that has a dominant position in the markets we serve, along with further diversifying our offerings to our customer base,”  said Rock Energy Systems CEO Barry Brandt.
