How Geothermal Technology Works
No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year.
The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the suns energy (heat) as it hits the Earth’s surface. WaterFurnace geothermal systems are able to tap into this free energy with an Earth loop. This technology is then used to provide your home or office with central heating and cooling.

Geothermal Heating Cycle
During the heating cycle, the fluid circulates through the loop extracting heat from the ground. The heat energy is transferred to the geothermal unit. The unit compresses the extracted heat to a high temperature and delivers it to your home through a normal duct system or radiant heat system.
Geothermal Cooling Cycle
For cooling, the process is simply reversed. Because the earth is much cooler than the air temperatures on a hot day, the geothermal system removes heat from the home and deposits it into the ground. The fluid is cooled by the ground temperatures and returned to the unit for cooling your home.
Comfort:
Geothermal systems heat and cool homes evenly, eliminating the hot and cold blasts of air found with conventional systems. Geothermal also dehumidifies the air during hot summer months.
Quiet:
Geothermal systems use the same principles that operate a refrigerator or freezer, and the units are just as quiet. There is no unsightly outdoor unit to disturb you or your neighbors.
Clean & Safe:
Geothermal units do not use fossil fuels such as natural gas and propane. Threats caused by combustion are eliminated. No worries about flames, fumes, odors, or carbon monoxide.
Free Hot Water Generation:
As a bonus, geothermal systems can produce some or all of your hot water at much higher efficiencies than ordinary methods. A simple connection is made so the geothermal system can deliver hot water to be stored in your hot water heater. In fact, the heat removed from your home during the cooling cycle is deposited directly to the water heater instead of the ground. This provides you with virtually free hot water.
Environmentally Friendly:
Geothermal is recognized by the United States Environmental Protection Agency as the most environmentally-safe, cost effective heating and cooling system on the market. Installing a geothermal system is equivalent to planting 750 trees or taking 2 cars off the road.
System Lifespan:
Ordinary systems require expensive regular maintenance for each unit – the furnace, the air conditioner, and the water heater. When properly installed, a GeoComfort geothermal system requires little or no maintenance beyond periodic checks and filter changes. Equipment life is prolonged since geothermal are located indoors and out of the varying climate and weather. Geothermal systems typically last more than 20 years if properly maintained.
