First developed in the 1850’s, a heat pump is a device that transfers heat from one location to another. It works by using safe refrigerant to absorb heat from one location (such as the outside air) and release it in another location (such as inside a building).
This cycle can be reversed in the summer to cool the building by absorbing heat from inside and releasing it outside. Heat pumps can be very efficient because they move heat rather than creating it, so they can provide heating or cooling at a lower cost than traditional heating and cooling systems.
