Here, it must be noted that our ground absorbs around half of the solar energy that our planet receives. Hence, the earth remains at a constant and moderate temperature below the surface throughout the year. On the other hand, the air temperature varies greatly during the summer and the winter season, as a result of which air source heating and cooling is not a much efficient system. The geothermal heat pumps takes the advantage of the constant temperature of the earth and uses a piping system known as the loop to heat and cool your homes. Water circulates within the loop exchanging heat between your home, the ground source heat pump and the earth.
When it comes to cooling your home with the help of geothermal heat pumps, it removes heat from your home and transfers it to the earth which is relatively at a constant temperature. As the temperature of the earth stays constant, it has been seen that ground source heat pumps or geothermal heat pumps are more efficient than the conventional heat pumps or the air conditioner. On the other hand, when heating of your home with the help of geothermal heat pump is required it extracts heat from the ground and transfers it to your home.
