Cold-Climate Heat Pumps
Cold-climate heat pumps (CCHPs) are the latest evolution in efficient air-source heat pump design. Thanks to an inverter—or variable speed drive—compressor design, these heat pumps achieve high levels of efficiency even during the winter season.
CCHPs operate with nearly 400% efficiency at 47°F or above. When temps drop to zero a CCHP will sustain efficiencies of about 200%. That means CCHPs deliver two to four units of heating energy for every one unit of energy consumed. CCHPs are so efficient they're able to provide up to 90% of space heating needs with an overall seasonal efficiency of 250%.
And just like other heat pumps, a CCHP doubles as a cooling system during the summer season.
CCHPs differ from standard air-source heat pumps in that they're:
- Rated with a higher Heating Season Performance Factor (HSPF). (To qualify for our rebates look for an HSPF of 9 or higher in ducted systems and 10 or higher in ductless mini-split systems.)
- Equipped with a variable capacity compressor, which gives them their incredible efficiency.
- Installed with a crossover set point of approximately 0°F to ensure heating season operation.
