Geothermal Heating 101

How does geothermal heating and cooling work?

Below the frost line (typically about 5-6ft), the temperature of the earth remains relatively constant between 10-15°C, even on days when it’s scorching hot or freezing cold above-ground. Geothermal heating and cooling in Ontario taps into a reliable, sustainable, and highly efficient source of heat – which is what makes it renewable thermal energy.

Geothermal heating and cooling uses a simple heat exchange process, harnessing stable below-ground temperatures to effectively heat and cool your home. Want to learn more about the installation of a geothermal heating and cooling system? Read more on installation here.

Geothermal Installation Peterborough

During the winter, a sealed piping system (called ground loops) draws heat from the ground into the home. A geothermal heat pump inside the home (in place of a furnace or other traditional system), upgrades this heat and circulates it through ductwork, underfloor heating, radiators, or air vents. In summer, the geothermal heat pump transfers warmth from the home back into the earth, keeping the home cool.

You’re probably already familiar with the heat pump technology used in geothermal energy systems – it’s used by your refrigerator. If you reach around the back of your refrigerator, you feel heat, but if you open it up, it’s cold. The refrigerator is removing heat from inside the fridge and expelling it into the kitchen. The refrigerator is not creating cold, it’s simply moving heat

Geothermal heating and cooling uses similar technology. It’s a heat exchange system that connects to the ground. Pipes recirculate fluid between the heat pump inside the home and the underground loops. As the fluid passes through the pipes it absorbs heat, allowing the pipes to transport warmth to and from the home. In the summer, the process is reversed for cooling, and the heat from the home is absorbed by the earth.

High-efficiency, sustainable heating and cooling

Affordable, year-round comfort

Temperature Control

Keep your basement the same temperature as your upstairs. Moving air continuously means more efficient, stable heating and a balanced temperature throughout your home.

Zero Emissions

A conventional furnace is essentially a controlled fire burning in a box, in your basement. Products of combustion can be dangerous if equipment isn’t well maintained. A geothermal heating and cooling system does not require combustion to provide heat, so there are no harmful byproducts to be concerned about.

Constant Heat Flow

A geothermal heating and cooling system circulates heat more continuously compared to oil, gas, or electric systems for steady temperature regulation. Your home shouldn’t feel like a temperature roller coaster.

Improved Air Quality

No-combustion heating and continuous air exchange mean better air quality in your home. Without a furnace intermittently drying out your air, you’ll also find your home has more stable humidity levels. Ask our experts about adding additional air quality measures like enhanced filtration systems in your home.
