Anesi gas heat pumps are air-to-water heat pumps and use natural gas, propane, or renewable gas as the primary fuel source. They use up to 50% less fuel and work at efficiencies well above 100% even in below zero temperatures.

Unlike traditional furnaces and boilers, the Anesi gas heat pump and all refrigerants, combustion processes, and venting are located outside. Only a warm water / food-grade glycol mixture enters the home through standard PEX or copper piping. Our natural refrigerant is environmentally friendly, will not harm the ozone layer, and will not break down into harmful, lifetime chemicals like PFAS.

Homes and businesses that use gas or propane for heating now have a solution that reduces their emissions at a lower cost and without sacrificing comfort and reliability, even at very low outside temperatures.
