The ceiling heating shows the highest rate of efficiency, which comes to 98% because the Carbontec material only has to go through the applied ceiling plaster and perhaps a textured ceiling finish. The efficiency of the floor heating comes to 60% because any floor radiant heat system has to overcome the floor-covering layer to provide heat into the room. Additionally, it isn't recommended you set your floor temperature above 80 degrees F as it can be harmful to walk on high-temperature flooring. When installed on the ceiling however the maximum temperature reached can be much higher allowing for the room to be warmed up faster.
