How geothermal heating and cooling works

A liquid is piped several hundred feet into the ground where the Earth’s constant ambient temperature of 55º Fahrenheit heats or cools it.

In winter, a heat pump installed within the building converts the Earth's thermal energy into hot air, which is circulated to keep residents warm. In summer, the heat pump draws warm air from inside the house into the underground pipes, where the Earth’s temperature cools it before it’s cycled back into the building.

As part of a network, this system can be shared among multiple homes and municipal buildings, reducing the total cost for each individual unit.
