Unlike furnaces, heat pumps don’t use fuel sources or generate heat. Instead, they rely on electricity and refrigerant to extract heat from the outdoor air and blow it into the home. What’s more, a heat pump can also work in reverse in the summer to extract warm air out of your home to cool it down.

Incorrectly sized and operated pumps can really sting on your electricity bills. … The problem with this is not so much their direct energy usage (as the pumps are small).

At what temperature do heat pumps become ineffective?

Heat pumps do not operate as efficiently when temperatures drop to between 25 and 40 degrees Fahrenheit for most systems. A heat pump works best when the temperature is above 40. Once outdoor temperatures drop to 40 degrees, heat pumps start losing efficiency, and they consume more energy to do their jobs.
