Take back the garage for year-round use. GG Series gas-fired, low-profile garage unit heaters are both residential and commercial outbuilding certified (non-occupied spaces only) in seven configurations to suit every area. Quiet, thermostat-controlled and easily installed–they stay out of the way and let you keep working comfortably.
The "XF/XC" Series units are highly efficient, extremely durable and designed so they can be installed in either standard or separated combustion venting configurations without requiring modification to the unit itself. Each with a 10-year heat exchanger, flue collector and burner warranty.
Sterling HVAC Shield propeller units are the perfect gas-fired heaters for use in moisture-corrosive environments such as greenhouses, waste water treatment plants or agricultural and food-service industries, thanks to a corrosion-resistant stainless steel exchanger and cabinet.
