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 option for climate control in homes and buildings. Heat pumps work by circulating a refrigerant through a system of coils. In heating mode, the pump extracts heat from the outside air, even in cold temperatures, and releases it indoors. In cooling mode, it reverses the process, removing heat from the indoor air and releasing it outside, providing a comfortable environment year-round.
