What Is Geothermal Heating?
Did you know that the temperature of the Earth remains relatively constant?
This is a surprise to many people, but in fact, the ground temperature is reasonably consistent, staying roughly between 50° and 60° all year long. A geothermal heat pump taps into this ground temperature and uses it to keep your home at a comfortable temperature.
There are three main components to a geothermal heating system:
- Ground heat exchanger
- Heat pump
- Ductwork or radiant floor system
The ground heat exchanger is buried in the ground, and the heat pump pulls warmth from the exchanger, disseminating it into your home through your air delivery system, such as your ductwork or your radiant floor tubing. Many people elect to use geothermal heat pumps as they are more energy-efficient than traditional HVAC systems. Geothermal systems also offer significant savings in your energy bills, and some reports suggest a savings of up to 75%.
