The Geothermal system is three times as efficient as any other heating system. Unlike oil, propane, gas or electric resistance, the geothermal system moves energy rather than producing energy or heat, via combustion or resistance.
Geothermal systems work by moving heat, rather than by converting chemical energy to heat.
Cooler air from the building is returned to the geothermal heat pump, where it cools the fluid flowing to the earth connection. The fluid is then re-warmed as it flows through the earth connection. In cooling mode, the process is reversed. The relatively cool fluid from the earth connection absorbs heat from the building and transfers it to the ground. The warm air from the building is returned to the geothermal heat pump, where it warms the fluid flowing to the earth connection.
