The basic idea of using warm water to distribute heat dates as far back as the Roman Empire. However, it was the development of the PEX distribution tubing that unleashed the concept's vast potential. The superior PEX tubing of cross linked polyethylene manufactured by Roth guarantees unparalleled long-term performance. Along with the other high-tech Roth innovations, it makes hydronic radiant heating your best choice for any home, building or remodeling project.

In buildings with radiant panel heating, thermostat settings are typically 3 to 6 degrees lower for three reasons:

• Temperature distribution all over the room is close to ideal. Therefore, normal thermostat settings can be decreased.
• About half the heat is provided as radiant heat, which most thermostats to do not read correctly. They mainly read air temperature; the portion of heat generated by convection or movement of warmed air.
• Because the feet are the thermostats of the body, when a radiant panel directly warms your feet, you feel comfortable at a much lower room temperature.
