Gas absorption heat pumps (GAHP) are a new addition to the heat pump category, although the core technology has been used for other purposes for a century. Instead of simply burning natural gas or propane and using as much of that energy as possible, GAHPs leverage the combustion heat to capture additional energy from the outdoor air. They are installed outside of the house and use natural gas, propane, hydrogen, or renewable natural gas blends and can operate at up to 140% efficiency, reducing fuel use by up to 50%. Gas absorption heat pumps cut carbon emissions by using less gas to achieve the same heating output as conventional gas furnaces and boilers. The refrigerant (R717) is natural, with zero ozone depletion potential (ODP), zero global warming potential (GWP), and no perfluoroalkyl and polyfluoroalkyl substances (PFAS). The Anesi HP80 gas absorption heat pump handles colder temperatures seamlessly. It can operate in temperatures as low as -40°F/C without backup and still produce plenty of comfortable heat and hot water. The gas heat pump will operate on a portable 30-amp generator if an area is prone to commercial power outages. Save money and reduce emissions by using less fuel. All refrigerant, combustion, and venting remain outside - keeping your family safe.
