If you are looking for a quiet system with low energy bills, no emissions and very low maintenance costs, then a geothermal unit could be the right choice for you!
Also known as Geoexchange or Ground Source Heating and Cooling, Geothermal systems use the thermal properties of the earth and take advantage of the stable temperatures underground to adjust the excessively high or low temperatures in your home.
One consideration is that the initial installation of a Geothermal unit does require that pipes are buried in the ground and therefore the excavation costs for retrofitting a system are sometimes considered prohibitive.
On the flip side, the low energy costs, the long life of the equipment—up to 50 years—and minimal maintenance means the upfront expenses can often be recovered over the life of the equipment. The lowest carbon footprint of any heating and cooling system, and minimal use of external power—just a small electric motor—makes Geothermal a popular choice.
In summary, if you have a Geothermal system in place, maintenance or replacement of above ground equipment is an excellent investment. For new home build choosing a Geothermal heating and cooling system is a very viable option. However if you already have an alternative system, and do not intend to stay in your home for many years, then a Geothermal system may not be the right choice for you.
How Geothermal Systems Work
The core principle is that the temperature several feet below ground remains constant all year round, irrespective of the weather conditions above ground. The system cools in the summer and heats in the winter, using the same temperature transfer principles, just in reverse.
Geothermal systems have two primary components—a heat pump, which typically resides in the basement of your home, and the “ground loop” pipe, which is buried underground.
In the Winter
During the winter, water is circulated through the ground loop and absorbs the (higher temperature) heat from the ground before it returns to the heat pump inside the house.
The heat pump extracts the heat from the water and distributes it throughout your home as warm air. The now cooler water is re-circulated to collect more heat from the ground.
In the Summer
The reverse process happens in the summer. The indoor heat pump takes hot air from inside your home and extracts the heat and transfers it to the water in the ground loop, leaving cool air to be recirculated through the air conditioning vents.
The now warm water passes through the ground loop buried underground where it is cooled by the ground temperature before being returned to the heat pump—and then the cycle repeats.
