If you want to upgrade your heat pump to make your home more energy efficient, it helps to know what your heat pump options are so you can make the best choice for your home. Here’s a quick rundown of the three types of heat pumps that may work in your Ventura or Santa Barbara home:
Air-Source Heat Pumps
An air-source heat pump uses an outdoor fan to blow air over two sets of coils that are filled with refrigerant to transfer heat indoors. Once indoors, a second fan then blows the heated air off of the coils and distributes it throughout your home.
Ground-Source Heat Pumps
Rather than absorbing warmth from the air, a ground-source heat pump absorbs heat from the ground itself or from underground water. To do so, it uses buried pipes filled with liquid in either an open or closed loop system. While the closed loop system circulates the liquid in a repeated loop, an open loop system returns the water it’s used to a well or other body of water where it gathers in more water to continue a steady circulation. The closed loop system generally uses refrigerant as the liquid, while the open loop system utilizes water from an existing source for its liquid.
Absorption Heat Pumps
Unlike most heat pumps that are powered by electricity, an absorption heat pump is powered by an alternative fuel source, such as solar power, natural gas or geothermal heated water. Another important difference is that the absorption heat pump doesn’t use refrigerant like the two other heat pump options listed above. Instead, it uses ammonia, which is absorbed into water and pressurized, then boiled out of the water by whatever source of heat the system uses for power.
