A heat pump, as part of a central heating and cooling system, uses the outside air to both heat a home in winter and cool it in summer. Basically, that means your heat pump will act as an air conditioner when things get hot and a heater when it’s cold outside – making heat pumps one versatile product. In addition to its flexibility, heat pumps are also energy-efficient. Think of a heat pump as a heat transporter constantly moving warm air from one place to another, to where it’s needed or not needed, depending on the season. In the winter, the pump extracts heat from the outdoor air or ground and distributes it to your home. In the summer, hot air from inside your home is removed – creating a cooler indoor environment.
