The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50°F to 70°F depending on geographic location.

Working with an underground loop system, geothermal heating and cooling systems utilize this constant temperature to exchange energy between your home/property and the earth as needed for heating and cooling via your Underfloor Heating or Radiators.

In winter, water circulating inside a sealed underground loop system absorbs heat from the earth and carries it to the geothermal unit. Here it is compressed to a higher temperature and sent as warm air to your indoor system for circulation throughout your home.

In the summer, the system reverses and expels heat from your home into the cooler earth via the loop system. This heat exchange process is not only natural, but is a natural and highly efficient way to create a comfortable climate in your home.

Loop Systems
There are several loop configurations available. They can either be vertical, horizontal, or submerged in a nearby pond or lake. In many cases, a water well can be used instead.

The best application will depend on the characteristics of your property. Your PRO-MECH / ECO-MECH adviser can show you which type of loop system is best suited for your property. These systems are widely regarded as being the most energy efficient and environmentally friendly Heating Systems available today.

For every 1 unit of electricity used to pump the heat, 3-4 units of heat are produced.
