A geothermal system may be almost invisible but it comes with a number of very “tangible” benefits.
- Geothermal eliminates outdoor equipment which means it’s stormproof against damage or corrosion by weather and lasts longer.
- There is no use of fossil fuel sources on-site so less pollution to the environment results. Fossil fuel costs are therefore zero. And there is no need to be concerned about flames or related accidents occurring.
- There is also no freshwater consumption in operation.
- A geothermal system operates very quietly and provides consistent, comfortable heating and cooling.
- Geothermal systems enjoy lower maintenance costs because of the absence of oil filters, nozzles, storage tanks or chimneys
- Notably longer operational life of the system: 25 years on average for the heat pump and an essentially permanent underground loop.
- Geothermal can be used to produce domestic hot water and for pool heating.
- A home equipped with geothermal will likely see its value increased
- Geothermal systems are by far the most efficient system available; a geothermal system converts a small amount of electrical energy into a large amount of heating and cooling
- Installation of a geothermal heat pump qualifies for a 30% federal tax credit (through 2016 currently) as well as various state, local and utility rebates
- Geothermal combined with a solar PV (photovoltaic) array that produces free electricity combines two renewables in one almost perfect system. This combination can reduce electric energy use to near zero, a situation called “Zero Net Energy” wherein during occasions when the solar system generates more power than a home or building is consuming (with some consumption coming from the heat pump(s), excess electricity is returned (“sold back” in essence) to the utility grid.
