Geothermal energy
Use the constant temperature of the earth for heating and cooling with money-saving geothermal technology.
How do geothermal systems work?
About four feet underground, the temperature of the earth stays the same all year long, about 55 degrees. A geothermal heating system uses pipes buried more than four feet deep in the earth.
The system pumps a liquid through the pipes to absorb the heat and brings it back indoors. A device called a "heat exchanger" takes the heat from the liquid and uses it to heat the air inside the home.
A geothermal system can cool your house during the summer, too! It just works in reverse, absorbing the heat from the air inside your home and moves it back into the earth.
A geothermal heater is also very energy-efficient. Almost none of the energy used is wasted, so it helps keep heating bills very low during the winter.

Unmatched benefits over traditional heating and cooling systems
- A geothermal system can cut utility bills by 30% to 50% compared to conventional heating and cooling systems.
- All equipment is protected indoors or underground.
- A life expectancy of up to 30 years; ground loops are often warranted for up to 50 years.
- Ground-source heat is naturally renewable and non-polluting.
- Both heating and cooling in one system.
- No dangers of gas leaks or carbon monoxide poisoning.
