Geothermal systems
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 heat exchanger takes the heat from the liquid and uses it to heat the home.
A geothermal system can also cool your house during the summer. It works in reverse, absorbing the heat from inside your home and moving it back into the earth.
Geothermal heaters are very energy efficient. Almost none of the energy used is wasted, so it helps keep heating bills very low during the winter.
