These are based on a steel carrier system with embedded water/heat transfer fluid pipes used to radiate or collect heat to and from the internal environment. They can use the air to water heat output of a TSC or be fed by other heating and cooling technologies.
TSC and composite floor slab linked for heat storage
The slab can be heated via water pipes embedded in the concrete, circulating water either warmed by heat pumps or a TSC to heat the internal environment.
Typically heating a room using traditional wall mounted radiators would need a water temperature of between 35-70ºC but the radiant floor slab is fed by supply temperatures of 30-35ºC. This reduces the heating load and also increases occupant comfort as the room is heated evenly using the floor.
