A heat pump is like having a two-for-one special, it’s an air conditioner and a heating system all in one. Much like an air conditioning system, a heat pump moves thermal energy across locations to make your home’s atmosphere more comfortable. During winter, a heat pump uses electricity to pull warm air into your home to provide heat. In the summer, it’s similar to an air conditioner—it transfers warm air from the inside to the outside and uses a refrigerant to cool and circulate cool air. Unlike an air conditioner, however, a heat pump provides thermal control almost the entire year, except for the extremely cold days in the winter.
Heat pumps use a small amount of electricity for power and produce more energy than they use. In Canada, the efficiency of a heat pump is rated by the Seasonal Energy Efficiency Ratio (SEER) and the Heating Seasonal Performance Rating (HSPF). The SEER is calculated by dividing the cooling output—measured in British Thermal Units (BTU)—by the amount of electrical energy consumed in watt-hours. The HSPF is the same calculation except for heating. The minimum SEER rating required in Canada for heat pumps is 13; the higher the rating, the more energy-efficient the heat pump. Heat pumps can reduce energy costs by as much as 50%.
Heat pumps have two main components: a condenser—installed on the outside of your home—and an indoor head unit that mounts on the wall or floor inside. The three types of heat pumps are air-source, water-source, and geothermal, as described below.
These systems are energy-efficient, quiet, and can be ducted or ductless. They provide heating by moving hot air from the outside to the indoors. For cooling, it does the reverse—moving heat from inside your home to the outside.
Ducted air-source heat pumps work similar to a central air conditioner and furnace system and are connected to the ductwork of your home. There will be an outdoor unit and an indoor coil in the furnace area; the temperature is then controlled by a central thermostat.
Ductless systems have a heat exchanger and a blower in a contained unit. They have an outdoor unit and will have one or more heads mounted throughout the interior of your home.
Water-source heat pumps are more energy-efficient than geothermal or air-source heat pumps, but typically require a large body of water. The stable temperature of the water, in comparison to air and ground temperatures, contributes to the efficiency of water-source heat pumps. Water-source heat pumps pull groundwater or water from a nearby source through the system. They extract the heat from the liquid and convert it to thermal energy to generate a heat supply for your home.
Geothermal heat pumps, also known as ground-source heat pumps, extract thermal energy from the soil. They typically consist of three main components:
