Under-Floor Heating Plate
August 1, 2010

Watts Radiant’s FlexPlate is primarily constructed with a specially processed natural graphite, which produces unique heat-conduction properties. Thermal efficiency is maximized through the use of lower-input water temperatures. In some cases, FlexPlate, which features a staple-up installation, will permit the use of lower-temperature sources such as modulating-condensing boilers, ground-source heat pumps and solar thermal.
