What is a Heat Pump?
A heat pump is a device that transfers heat from one place to another, from in to out or from out to in. In the winter it works like a heater, extracting heat energy from outside and transferring it inside. In the summer the process reverses and it will remove heat from your home and transfer it outside like and air conditioner.
There are many different names and types of heat pumps but they can all be categorized as one of three different types; air source, water source or geothermal.
An air source heat pump transfers energy in the air from one place to another . It uses an outdoor heat exchanger coil to extract heat from the air and an indoor heat exchanger coil to transfer the heat into air ducts, radiators or a hot water tank. This process can also be reversed so that it may be used as and air conditioner as well.
A water source heat pump operates similarly to the air source but uses water instead of air to transfer heat. These forms of pumps are not available to everyone because of the resources needed, but if you live near a well, lake or other natural resource this can be a viable option. A water source heat pump cycles water through a series of pipes that are laid out in water. As the water cycles it collects the heat and transfers that energy into your home. Again this process reverses in the summer and carries heat out of your house, also by way of the water in the pipes.
A geothermal unit is also referred to as a ground source heat pump. In this system, the pump uses the earth as its heat source. Conceptually, it is the same as and air source or water source heat pump, and there are two different methods of installation.
A horizontal ground coupled system buries horizontal piping 4 feet or more under the ground and circulates a fluid like antifreeze or water through it.
A vertical ground coupled system has the same process as its horizontal counter part but the pipes are buried vertically.
