A Simplified Guide to Geothermal Heating Systems

December 28, 2014

Geothermal heating systems have a well-deserved reputation for being highly efficient and cost effective. The following guide will help you understand how geothermal heating works and what you can expect if you decide to install a geothermal heating/cooling system in your beautiful Florida home.

Benefits of a Geothermal Heating System

Geothermal heating systems can be amazingly efficient, according to the Environmental Protection Agency, and often reach efficiency levels of 300 to 400 percent. Geothermal equipment achieves this efficiency because it uses a heat pump to capture heat and move it from place to place instead of burning fossil fuels to produce heat. The largest energy expenditure in a geothermal heating system is the electricity used to power the equipment.

Components of a Geothermal System

A geothermal heating system consists of important components installed inside and outside your home. The inside components include the heat pump itself, plus heat exchangers and air handling fans that distribute warmed air throughout your home. The outside components consist of an expansive network of pipes, called a loop, that’s buried in the ground at a depth where the soil temperature stays about the same all year. The loop contains water or a water/antifreeze solution that circulates between the indoor and outdoor components.

Geothermal Function

As the liquid in the loop pipes circulates, it either absorbs or releases heat. When the system is cooling your home, the heat is captured from the indoor environment and transferred to the liquid in the loop. The liquid circulates to the outdoor pipes, where the heat is released.

When producing heating, the liquid flow is reversed, allowing it to absorb heat from the ground outside. The heated liquid flows back inside where heat exchangers transfer the heat to warmed air that is blown into the ductwork and out at registers inside your home.
