Installing A Geothermal Unit

No matter what climate you live in, the temperature throughout the year fluctuates. For some climates, this means blazing hot summers and frigid winters. What many people don’t realize is that, despite the seasons, the temperature below ground stays fairly consistent. Installation of geothermal energy such as a ground source or heat pump can be done year round. The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the sun’s energy as it hits the Earth’s surface. WaterFurnace geothermal systems are able to tap into this free energy source with an earth loop. This technology is used to provide your home or office with central heating and cooling.

How Geothermal Energy Does Heating?

During the heating cycle, a WaterFurnace geothermal system uses the earth loop to extract heat from the ground. As the system pulls heat from the loop, it is distributed through a conventional duct system as warm air. The same energy can also be used for a radiant floor system or residential hot water heating.

How Geothermal Energy Does Cooling?

In cooling mode, the WaterFurnace geothermal system will air condition your home by reversing the heating process. Instead of extracting heat from the ground, it’s extracted from your home and moved back into the earth loop or used to preheat your hot water tank. Once the heat is removed from the air, it’s distributed through the duct system in your home.
