20 seconds: how a geothermal system heats and cools
The ground does the hard work
A buried loop and an indoor heat pump. No flame, no outdoor unit.
The earth stays steady
A few feet down, the ground holds 50 to 55°F in January and July.
Heat comes up
Fluid in the loop gathers earth heat. The heat pump concentrates it and sends warm air through your home.
Heat goes down
The system reverses. Heat leaves your home and goes back into the cool ground.
Hot water too
A desuperheater can cut water heating costs by up to 50%.
