Are you interested in a heat pump but unsure whether it will work when temperatures fall below freezing? Modern heat pumps can effectively heat and cool homes in cold climates, including Minnesota.
Why Consider a Heat Pump?
As Minnesota’s heat pump market grows, installation is becoming more cost-effective. New systems can reduce energy consumption by as much as 55%, with the greatest savings often found in homes using electric resistance or propane heat.
How Do Heat Pumps Work?
Heat pumps move heat rather than create it. In winter, they extract heat from outdoor air and transfer it inside. In summer, they reverse the process and operate like a traditional air conditioner.
Cold-climate equipment is highly efficient down to 5°F, and some systems can provide heat at temperatures as low as -20°F. This reduces, but does not eliminate, the need for backup heat. With the correct settings, a heat pump can keep your home comfortable during most Minnesota winter days.
Why Are Heat Pumps So Efficient?
Even the most efficient boiler or furnace loses some energy during combustion. High-efficiency heat pumps, however, can reach efficiencies of 400% or more, delivering four or more units of heat for every unit of energy used.
Variable-speed, inverter-driven compressors help make this possible. These systems adjust their speed to match a home’s heating or cooling needs, maintaining a steadier temperature and operating more efficiently than traditional equipment that frequently turns on and off.
Do All Heat Pumps Work Below Zero?
No. Standard heat pumps typically provide efficient heat down to about 20°F. They cost less than cold-climate models and may still be a good choice, depending on your needs and goals. Although they cover less of the home’s heating load, they can reduce energy use and lower utility bills.
Are Rebates Available?
Meeker Energy offers rebates for qualifying heat pumps enrolled in its dual fuel and cycled AC energy management programs. Visit www.meeker.coop/programs/ to learn more.
