How a Heat Pump Works

Heat pumps are an energy-efficient alternative to air conditioners or furnaces, and are primarily used for climates that need moderate heating or cooling. But most people aren’t aware of just how heat pumps work. 

Heat pumps use electricity like a refrigerator, in order to make a cool space even cooler, and a warm space warmer, as the pump moves heat out of a cool space and into a warm space. Because they simply move heat rather generating it, heat pumps are able to put out up to 4 times the amount of energy that the pumps consume. If you use electricity to power your heat pump, it can cut down on the electricity you use to heat or cool your home by 30% to 40% when used on a regular basis. 

In the wintertime, heat pumps draw heat from the cool outdoors into your warm house, while in the hot summertime, it expels heat from your house into the warmer outdoors. Heat pumps are highly efficient, and they dehumidify the air in your home better than the more common central air conditioners used by most homes. Using a heat pump also requires less energy and can make your house cooler in the summer months. However, the efficiency of most air-source heat pumps as a heat source drops dramatically at low temperatures, generally making them unsuitable for cold climates, although there are systems that can overcome the problem. 

Making the choice of a heat pump for your home is an important one, something that you should discuss with your HVAC contractor in order to make the best selection for your needs and those of your family.
