Geothermal systems have been around for centuries that help people stay comfortable regardless of the weather. Early man sheltered in caves for even temperatures year-round and people today tap into the ground beneath them for the same relief from the heat and cold.
A geothermal heat pump (GHP) uses the stored energy underground to provide heating and cooling. It uses loops filled with a liquid that are buried deep underground. The liquid absorbs the temperature of the ground and as it circulates through the system, it transfers the thermal energy. In the winter, the liquid absorbs heat from the ground that the system’s compressor pressurizes to intensify. In the summer, it takes heat from your home and deposits it underground.
Benefits of GHPs
Although geothermal systems are the most energy efficient HVAC system available, they’re also the most expensive, largely due to installation costs. However, they do pay for themselves quickly by cutting energy costs substantially. More benefits include:
GHPs use no fuel. Heat pumps don’t use fuel to make heat. Instead, they extract it from the air or ground. The systems are extremely efficient. In fact, a GHP is the most energy efficient HVAC system currently available. Unlike an air-source heat pump, a GHP doesn’t have to battle outdoor temperatures that have wide swings compared to the steady temperatures underground.
GHPs last a long time. The normal lifetime of an air-source heat pump ranges from 10 to 15 years. A GHP’s loop field lasts over 50 years while the indoor air handler lasts 25 years and more.
They’re quiet. A GHP runs quietly because it doesn’t require an outdoor condenser, which also saves yard space.
Financial incentives are available. A federal tax credit in the amount of 30 percent is available through 12/31/2019 for the purchase and installation of a GHP. There’s no cap on the amount you can claim.
