Uponor, formerly Wirsbo, was the first to bring PEX radiant floor heating to North America more than 40 years ago. Today, Uponor radiant floor heating systems are bringing the energy-efficient luxury of radiant floor heating to the masses for a simple, affordable solution to home comfort.In an Uponor radiant floor heating system, warm water flows through flexible, durable crosslinked polyethylene (PEX) tubing that is embedded under the floor. The warmth radiates up from the floor to warm objects and people in a room. It is the purest form of human thermal comfort.
The water in a radiant system has a capacity to transport energy 3,500 times greater than air, so it can heat (and even cool) using less energy than a forced-air system. This amounts to greater comfort at a lower thermostat setting, which provides lower energy bills. In fact, more people are comfortable with radiant floor heating at a lower thermostat setting than with forced-air heating at a higher thermostat setting.
