How Heat Pumps Work
Heat pumps work by transferring heat energy from the air. In the winter months, the heat pump extracts heat from the air outside and transfers that into the house to warm the air indoors. Yes, there is heat energy in the outdoor air even when it is cold outside. In the winter months, the system reverses the process and extracts heat energy from the air in your home and transfers it outside. This cools the air inside the house, providing both heat and air conditioning in one unit.
Air source heat pumps are the most common. Another that is gaining popularity is geothermal heat pumps. These work in a similar way, but extract heat energy from under the ground and bring it into the house. When choosing a heat pump for your home, it is important to get the right size to ensure optimal comfort.
