Geothemal Energy

Geothermal Energy is energy that is stored in the ground from the sun. At six feet below the surface, the earth’s temperature is a constant 10-15C (40-60F) all year round. This energy is a steady heat source, even in the coldest winter. A Geothermal system can replace your conventional furnace and even cool your home in the summer. It works by installing closed loop piping into the ground either horizontally or vertically. These pipes are connected to a Geothermal heat exchanger unit inside your home and a fluid is pumped through the pipes. As the fluid travels through the pipes, it is heated by the ground. When the fluid returns to your home, the heat is transfered into the heat exchanger and pumped throughout your home via radiatorss or in-floor radiant heating.  This system can also be used to heat domestic water. Apart from the initial investment, which is usually recouped in 7-10 years, the only cost to operate the system is the small amount of electricity required to run the pump. The additional benefit to Geothermal is in the summer you can reverse the flow and the system will draw the heat from your home and absorb it into the ground providing a constant temperature all year round. Geothermal, a constant renewable source of energy producing zero carbon emissions.
