A few meters beneath the surface is a vast amount of stored renewable energy that we can utilise with Geoexchange. The earth’s temperature remains fairly constant and is constantly being recharged by the sun.
It is the use of this stored renewable energy that we can use to your advantage to provide extremely efficient heating and cooling.
In winter, a water solution circulating through pipes buried in the ground absorbs heat from the earth and carries it into the home. Inside the home a heat pump is utilised to concentrate the earth’s thermal energy and then to transfer it to either water for a hydronic underfloor, a hydronic radiator system or to air circulated through ductwork to heat the home.
In the summer, the process is reversed. The heat inside the home is extracted from the air and transferred through the heat pump to the ground loop piping. The water solution in the ground loop then carries the excess heat back to the earth.
