Geothermal Energy: The World's Greenest Heating and Cooling System
Looking for an efficient, cost effective, and environmentally friendly heating/cooling system? A geothermal heat pump is the greenest way to go. Learn the facts about geothermal energy.
- An EPA study of energy efficiency concluded geothermal energy is the most environmentally friendly heating/cooling system.
- The United States National Renewable Energy Laboratory concluded that geothermal energy is more efficient and cost-effective compared with conventional residential systems.
- Available everywhere in the United States, geothermal energy can be found underground virtually anywhere.
- Geothermal cost savings can be increased by geothermal energy incentives, available from federal, state, local, and utility sources.
Energy and cost savings of geothermal heat pumps will vary by region and type of conventional system they're compared with. But the energy cost of geothermal versus conventional HVAC systems will always be lower — and the geothermal system will always be greener.
Geothermal Heat Pumps
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.
During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
In the cooling mode, the heating process is reversed - creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
Geothermal vs. Geoexchange: what's in a name?
Geothermal energy has been used to heat and air condition buildings for several decades, and, during that time, these geothermal systems have been called many different things. Some of the more popular variations include geo-thermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, and even our company name, water furnace heating and cooling.
