At what temperature is a heat pump not effective?
If you are impatient, I won’t make you wait; heat pumps don’t work well below 25-30 degrees Fahrenheit. But what you might not know is that the heat pump temperature range is broader than most people think, and with the addition of supplemental heating it can work even in the chilliest of temperatures.Click to see…

Consequently, what temperature does a heat pump stop working?As the outdoor air temperature drops, the heat pump needs to work harder, so it becomes less efficient. The COP continues to drop until we reach an outdoor temperature of -4°F (-20°C). -4°F is the lower limit of our air source heat pump effective temperature range.Similarly, how well does a heat pump work in cold weather? When temperatures are mild, the heat pump keeps your operating costs low. During extreme cold, the backup gas-fired heater kicks on to maintain high energy-efficiency levels. Since heat pumps move heat rather than generate it, they are much more efficient in temperate climate zones. Correspondingly, do heat pumps work below 20 degrees? Historically, below 20 degrees, air-source heat pumps drop in efficiency to 100 percent (no better that electric radiant heat). They do not drop below 100 percent efficiency. Some people even experience cold homes when low temperatures are extreme because the heat pump simply can’t produce the needed heat fast enough.Should I set back the temperature on a heat pump?You should talk with your contractor about the specifics of your system, but in general, we do no recommend a setback temperature of more than 5 degrees with a heat pump in heating mode.
