How Geothermal Systems Work



Geothermal heating and cooling systems are becoming more and more common in Lexington homes and businesses. Their highly efficient use of clean, natural energy allows users to cut costs while maintaining comfort. Have you ever wondered how a geothermal system operates? Below is a look at how geothermal works.

Clean, natural energy

A geothermal heating and cooling system uses the energy that exists below ground to heat and cool homes and buildings. Below ground, temperatures remain constant all year long, and provide enough energy to offer adequate indoor heating even on the coldest days. Geothermal systems utilize only a small amount of electricity to transfer heat and burn no fossil fuels, making them a cleaner, greener alternative to traditional heating and cooling systems. Geothermal energy is a renewable resource, and there is plenty available right beneath your own home!

How geothermal works

A geothermal heating and cooling system is composed of two main parts: a heat pump and a ground loop. The ground loop is a network of buried, fluid-filled piping that is typically installed vertically or horizontally on your property, or connected to a water source. The ground loop moves energy between the earth and your home, and the heat pump distributes it in your living areas.

Heating and cooling

Geothermal systems can be used to heat and cool a home or building. During winter months, below-ground energy is absorbed by the ground loop and moved to the heat pump, which then transfers the heat into your living areas as needed. In the summertime, the heat pump extracts excess heat from your living areas and transfers it to the ground loop. The excess heat is deposited back into the earth or into a water source, depending on your system’s configuration.

Installing a geothermal heating and cooling system will lower your energy costs while providing reliable, year-round comfort. For an estimate, please contact GreenBox Home Services today.
