An electric heat pump is a device that transfers heat from one place to another using electricity. It can both heat and cool spaces by moving heat indoors during winter and outdoors during summer. This makes it an efficient alternative to traditional heating systems like furnaces. Heat pumps work by circulating a refrigerant through coils, absorbing heat from the air or ground. They are known for their energy efficiency, as they can provide more heating or cooling energy than the electrical energy they consume. This efficiency can lead to lower energy bills and reduced greenhouse gas emissions.
