ThermaPANEL is a modular heat exchange system that efficiently heats or cools pedestal or ground mounted pavers. The Therma-HEXX system can be used with wood, stone, cobbles, bricks or any cast in place type of pavement as well.

Compare the efficiency of the ThermaPANEL system over the traditional radiant tubing systems. Panel Inlet and outlet connection tubes are .625" OD (1/2" CTS). Panels have a fluid capacity of .26 gallons with a minimum water flow rate of 1 GPM @ 24 psi head pressure with a maximum pressure drop of 1.06 psi.

Panels weigh about 1.6 lbs. per square foot including fluid and 1 lb. density. Panels shall have a minimum 1" thickness of rigid EPS or XPS foam insulation attached to the underside of the panels. Panels will be connected to each other with tubing of similar material to that of the panels using fusion welding technology. For more information visit www.therma-hexx.com.
