What is Geothermal Heating and Cooling System?
If you’re looking for an energy-efficient and environmentally friendly way to heat and cool your home, a geothermal heating and cooling system may be just what you need. These systems utilize the renewable energy from the earth’s heat to regulate the temperature of your home, providing a comfortable living space all year round.
At its core, a geothermal heating and cooling system relies on a basic principle: the earth absorbs and stores energy from the sun in the form of heat. This heat is then available for use, and by tapping into it, we can heat and cool our homes without relying on non-renewable energy sources like oil or gas.
Unlike traditional heating and cooling systems, which rely on burning fuel to generate heat, a geothermal system works by transferring heat between the earth and your home through a series of pipes, or loops, that are buried underground. These pipes are filled with a special liquid called a refrigerant, which absorbs heat from the earth and carries it back to your home.
Once the heat is transferred to your home, it can be used to heat the air or water in your house, or to power a radiant heating system. In the summer months, the system works in reverse, absorbing heat from your home and transferring it back to the earth to keep your living space cool and comfortable.
How Does a Geothermal Heat Pump Work?
A geothermal heat pump, also known as a ground source heat pump, uses the earth’s natural heat as an energy source to heat or cool a building. The geothermal heat pump system works by circulating a fluid, usually a mixture of water and antifreeze, through a series of pipes buried in the ground or submerged in a pond or lake.
The fluid absorbs heat from the earth and carries it to the heat pump, which extracts the heat and transfers it to the air or water used to heat the building. In cooling mode, the process is reversed, with the heat pump removing heat from the building and transferring it to the fluid, which is then returned to the ground.
