Frequently Asked Questions
Q: How efficient are geothermal systems?
A: Geothermal systems are the most energy efficient heating and cooling systems available today, with efficiencies of 300% to 400%. No other heating and cooling systems can match the energy efficiency and environmental benefits of geothermal systems. And that translates directly into savings on your utility bills.
Q: Can one system provide both space heating and cooling for my home?
A: Yes. A geothermal system can be a combination heating/cooling and hot water heating system. You can change from one mode to another with a simple flick on your indoor thermostat. Geothermal systems can be designed to efficiently heat domestic hot water, swimming pools, hot tubs, and radiant in-floor heating systems.
Q: How much space does a geothermal system require?
A: In residential applications, the heat pump units require about the same amount of space as a traditional furnace. In commercial applications, geothermal systems often substantially reduce the space required for a mechanical room — allowing more of the building to be used productively.
Q: How long will a geothermal system last?
A: Geothermal systems are durable and highly reliable. They contain fewer mechanical components, and all components are either buried in the ground or located inside the building, which protects them from outside conditions. The high-density polyethylene pipe used in the ground loops carries a 50-year warranty.
Q: How noisy are geothermal systems?
A: Very quiet. Geothermal systems provide a pleasant environment inside and outside of the home. GSHP’s have no noisy fan units to disturb outdoor activities, on or near the patio.
Q: How safe are geothermal systems?
A: Geothermal systems are safe and protected. With no exposed equipment outdoors, children or pets cannot injure themselves or damage exterior units. Ground source heat pumps have no open flame, flammable fuel or potentially dangerous fuel storage tanks.
Q: What about comfort?
A: Geothermal systems move warm air (90–105°(F) throughout your home or business via standard ductwork. An even comfort level is created because the warm air is moved in slightly higher volumes and saturates the building with warmth more evenly. This helps even out hot or colds spots and eliminates the cold air blasts common with fossil fuel furnaces. Geothermal systems are also well suited for in-floor radiant heating and tile warming.
Q: Can these systems be used for commercial, industrial, or institutional buildings?
A: Yes! We have installed geothermal systems in schools, churches, hotels, office buildings, recreational facilities, and large multi-residential developments. Ground source heat pumps can also supply heat for many industrial processes. Geothermal systems are suitable for just about any heating or cooling application.
Geoexchange systems have the lowest life cycle costs compared to other space heating and cooling systems.
The earth loop can be expected to last 50-70 years.
