Powered by a highly efficient natural gas engine, the water heater module extracts energy from the atmosphere and pumps the heat to useful temperatures. Free waste heat from the engine is captured and repurposed, adding to the unit’s capacity and efficiency. Ideal for commercial and industrial sites with substantial hot-water requirements, the high-efficiency water heater offers up to twice the efficiency and one-half the fuel consumption of a conventional gas-fired boiler, claims the company. The heat pump with reclaimed engine waste heat results in a coefficient of performance (COP) of 1.2 to 1.8. It can produce 400,000 to 600,000 Btuh of hot water, which can be used for commercial domestic hot water, process hot water, or space heating in commercial buildings and manufacturing facilities.
