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 higher levels of efficiency even during the winter season.
CCHPs operate with nearly 400% efficiency at 47°F or above and when temps drop to zero can 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 and offer an effective season efficiency of 250%. This makes them one of the most efficient electric heating options available today!
And just like other heat pumps, a CCHP doubles as a cooling system during the summer season.
CCHPs are air-source heat pumps with a high heating season performance factor (HSPF). CCHPs differ from standard air-source heat pumps in that they're:
- Rated with an HSPF of 10 or higher.
- Equipped with a variable capacity compressor.
- Installed with a crossover set point of approximately 0°F to ensure heating season operation.
Save with off-peak rates
Installed as part of an off-peak heating system, a CCHP will save you even more with a discounted rate to lower your operational costs. Systems are controlled during occasional peak periods. On the Dual Fuel Rate your back up non-electric system will take over. On the Deferred Load Rate, a heat storage system will fill in. And during the summer CCHPs installed on one of our off-peak rates, including Dual Fuel or Deferred Load, may be cycled on and off every 15 minutes during occasional peak periods. It ensures that spaces stay cool and comfortable, helps us to manage summer’s peak demands, and lets you save on cooling costs with a reduced rate.
CCHPs installed on a general service rate (rather than an off-peak rate) or on the Residential Demand Control Rate are eligible for cycled control during the summer season through the CoolSavings program. Customers enrolled in CoolSavings receive a monthly bill credit during the summer season (June through September). Bill credits vary by state.
Generous CCHP rebates are available for qualified energy-efficiency or off-peak equipment installations. Rebates vary by state and average $600 per ton!
Note: Minnesota locations with primary natural gas heating may not qualify for energy efficiency rates. Off-peak rebates are available.
