Air-to-water heat pumps

Air-to-water heat pumps (AWHPs) are an emerging technology that improve the efficiency of hydronic underfloor heat storage systems by using free energy available in outdoor air and transferring it through a liquid for heating. Some AWHPs operate efficiently down to -10°F while maintaining efficiencies above 150%. And systems can include electric resistance backup heating for the coldest weather.

Benefits of AWHPs

Air-to-water heat pumps:

• Provide a high-efficiency new or replacement option where an electric boiler would typically be used.
• Are a great alternative for locations where geothermal isn't feasible due to land space requirements.
• Can be designed to provide domestic hot water (DHW) preheating to increase energy savings.
