Geothermal Heating.pdf

Geothermal energy is a consistent, comfortable, and cost-effective way to heat and cool homes. It works by extracting low-grade energy stored in the earth's crust, which is provided by the sun and the earth's core. A geothermal system consists of a ground loop, a heat pump, and a distribution system. The ground loop is a series of pipes buried underground that circulates a fluid to absorb or release heat. The heat pump concentrates the low-grade energy and distributes it into the home via air ducts or an in-floor heating system.

There are three types of ground loops: open loop, horizontal closed loop, and vertical closed loop. Each has its benefits and is suitable for different property types or locations. The open loop system uses an existing or freshly drilled well, while the horizontal and vertical closed loop systems use pipes laid underground or in a vertically drilled borehole.

The distribution system delivers the heat into the home in the form of hot air or hot water. There are three choices: ducted systems, in-floor systems, and all-in-one systems. Ducted systems use forced air ductwork, while in-floor systems use pipes installed under the floor to distribute heat.

Geothermal energy is a low-temperature heat source, providing a consistent and comfortable temperature in the home. It is an environmentally and financially responsible choice, with potential savings on energy bills. The cost of installing a geothermal system can be recouped in a short number of years through reduced energy bills.
