Understanding Heat Pumps
There are three types of heat pumps can help heat your home in the winter.
In the summer, air conditioners remove heat from the house and push it outside. In the winter, air-to-air heat pumps operate in reverse. They remove heat from the outside air and bring it into the house. They are attractive because they are less expensive to operate than many types of heaters.
Unfortunately, heat pumps become significantly less efficient and therefore more expensive when the outside gets colder. For that reason, using heat pumps is best when temperatures stay above 30 degrees Fahrenheit.
Another similar type of heat pump is a ground or water-source heat pump. These units extract heat from the ground through either a closed or open loop. Since the average ground temperatures stay around 50 degrees year round, this may be a good option for both heating and cooling for some. The downside is a system can be quite costly to install and maintain.
A third type of heat pump is a geothermal heat pump, also known as GeoExchange. These heat pumps utilize the warmer temperatures below the earth’s surface in the winter and relative cooler temperatures in the summer to both heat and cool. A GHP takes advantage of the heat differences and exchanges heat with the earth through a ground heat exchanger.
The downside for GHP are the installation costs. The U.S. government estimates that although the systems can costs several times that of an air-source system, the additional costs are returned to you in savings in as little as 5 to 10 years. A system is estimate to last for 25 years for the inside components and 50 plus years for the ground loop.
Many customers use a combination of a heat pump along with a traditional heating system to cost effectively heat their homes in the winter. If you are considering your home’s heating and cooling needs, give Classic Aire Care a call today. Our experts will discuss what options we have for you.
