Heat pumps are very effective for homes. A heat pump is an all-in-one heating and air conditioning system that works year-round for comfort. During warmer months the heat pump works as a normal air conditioner. In colder weather, a heat pump collects heat from the outdoor air and transfers it inside the home. On very cold days when there’s not enough heat in the outside air to meet the thermostat setting, an electric heater supplements the indoor air to warm a home. This process is quite efficient as it produces two to three times more heat than the energy it uses. With this dual-fuel option, the two systems share the heating load, but never simultaneously, each system operates when it is most cost effective.
