Renewable Energy for Heating and Cooling

A vast reservoir of thermal energy lies in store directly beneath the buildings we occupy. This energy, originating from the sun and absorbed by the ground, can provide clean, renewable heating and cooling.

Using only a small amount of electricity, a geothermal system collects heat energy from the ground and delivers it to the building for winter heating. With a flick of a switch on your thermostat, the process is reversed for cooling.

Proven Technology
Geothermal technology has proven itself time and time again, through thousands of installations. Experience has lead to great strides in the efficiency and durability of ground source heat pumps, but the ground loops have remained relatively unchanged since the industry’s inception. Until now.

REHAU offers an innovative ground loop solution drawing on our expertise as the pioneer of PEXa heating pipe. Our RAUGEO ground loop heat exchange system, with its unique design and materials, offers a revolutionary new way to do geothermal.
