Panel Radiators
European-style radiator with an integral valve suited to receive a non-electric thermostat. The surface temperature of the unit changes to match the room set point requirements. An oversized radiator to accommodate low-temperature hydronics will never get hot to the touch. Many say this is the next best thing to radiant floor heat — a heating solution that has a small footprint and is easy to clean around. These models can be recessed for a flush clean look. The name says it all — a complete radiator with an invisible pipe system and integrated thermostatic radiator valve.
