Heat pumps take heat from the air, the ground or a body of water and transfer it to heat the space or hot water inside your home.
Essentially operating as a fridge in reverse, a heat pump takes heat from the outside and releases it indoors, where a refrigerator takes heat from inside and releases it outside.
The refrigerant technology within a heat pump allows the unit to produce up to 4 units of heat for every unit of electricity consumed by running the unit, making them a very efficient, cost-effective means of providing space and water heating.
