Do Heat Pumps Work Below 20 Degrees? (Critical Choice)


Your new heat pump worked well this summer. It did so by pulling warm air in from outside and drawing it into your home’s air vents. But as winter approaches, how can a heat pump do its job with little heat in the atmosphere for it to extract?

Do heat pumps really work when it’s below 20 degrees? Yes, they do, but not very efficiently.

Here are some of the key points that I’ll cover, plus more you’ll need to know:

• The optimum temperature range for heat pumps
• Specifics on how heat pumps work
• How heat pumps work in regions that suffer from extreme cold
• Electric backups for heat pumps
• Protecting your heat pump from extreme cold

Heat pumps work best in moderate temperatures. When temperatures drop below freezing, these pumps must have helped. If you deal with extreme cold in your region and would you’d like to learn more, please read on.

Temperature Range Outdoors for Most Effective Heat Pumping

There is enough heat energy in the air when the temperature is above 40 to heat your home. But, as the temperature falls, heat pumps must use more energy to do their job.

By the time the temperature drops below freezing, it ceases being the efficient appliance it usually is in temperate climates.

When the thermometer drops to 20 degrees, your heat pump will need auxiliary power. There isn’t enough heat in the outside air for your pump to extract.

Connect your auxiliary heating system to your heat pump system so that it will turn on as soon as the outside temperature gets too low for your pump to handle.

Try adding heat strips inside your HVAC system. They will shoulder some of the heating chores your heat pump can’t handle at low temperatures.

Use a gas furnace as a backup. At low temperatures, gas remains an efficient and reliable source of heat.
