Geothermal energy is simply heat energy from the Earth. The underground reservoirs of hot water, steam, and hot rocks can be tapped into to generate electricity or be used for heating and cooling purposes in buildings. Geothermal energy can be captured through geothermal power plants or geothermal heat pumps. Here’s more on how it works on the latter.
How Geothermal Energy Works With Heat Pumps
If you are thinking of adding a heating system to your home, geothermal heat pump installation Gilbert, AZ is an ideal option to consider. A geothermal heat pump system relies on the earth’s constant temperature as the medium of exchange for heat. Ground temperatures often vary depending on latitude. In summer, the ground temperatures tend to be cooler than the air above it and warmer in winter.
Some areas experience occasional temperatures extremes defined by sub-zero cold in winter and scorching heat in summer. Therefore, the heat pumps are often installed just a few feet below the surface of the earth where temperatures are relatively constant.
A geothermal heat pump system is made up of a heat exchanger, the heat pump itself, and a ductwork system. In winter, the heat pump works by removing heat from your heat exchanger then pumping it into your indoor ductwork system. In summer, heat is removed from the indoor ductwork and pumped into the heat exchanger. Geothermal energy is clean and sustainable, which makes the geothermal heat pump an energy efficient heat pump.
Types Of Geothermal Heat Pump Systems
There are different types of heat pumps including closed-loop, vertical, horizontal, and pond/lake systems. Closed-loop systems have one loop inside the system cabinet and two loops located on the ground. The ground loops bring the heat while the inside loop exchanges it. For accuracy and proper functioning, closed-loop systems have bigger and longer pipes.
Vertical and horizontal systems are specialized types of the closed-loop system. The major difference is in how the pipes are laid out. For vertical systems, the pipes are laid vertically, which is ideal in areas with limited amount of land. However, it is often challenging to install this type of heat pump in rocky grounds. Horizontal systems tend to be more effective but will require plenty of land for installation.
Pond/lake systems require a nearby water source such as a pond or lake for installation. Concentric coils or pipes are then run from your building and laid out in the water.
