These sounds occur when the required high temperatures come into contact with cooler plates. There is a long history of underfloor aluminum plates making irritating expansion noises when turning on the system. Radiantec and other radiant heat transfer plate systems result in much higher lifetime operating costs due to the hotter water temperature required to heat the room. In contrast, an efficient radiant floor heating system like Thermalboard will save you thousands of dollars in energy costs over the lifetime of your building. Put simply, a high supply water temperature requirement will lower the system’s efficiency, since it must work much harder to maintain a comfortable level of heat. The heat from the boards makes direct contact with your floor resulting in the fast and efficient delivery of comfortable radiant heat.Įxample: Thermalboard only requires a supply water temperature of 108☏, compared to an underfloor aluminum plate system, which requires a whopping 145☏ water temperature for the same heat load! Our radiant heat panels are covered in a layer of highly conductive aluminum and are installed above the subfloor, rather than below. Additional heat is lost downward as it fills the floor cavity.ĭue to their inefficient design, underfloor systems require far higher water temperatures than Thermalboard. The heat generated from the water in the tubes must overcome the resistance of the poor conducting subfloor. Underfloor heat transfer plates sandwich PEX tubing against the underside of the floor. Understanding the Poor Efficiency of Radiant Heat Transfer Plates Our panels are constructed with highly conductive aluminum that is installed directly beneath the floor - resulting in greater efficiency and a much faster response time.
Slower Response Timeīecause the PEX tubing is so far away from the floor, it takes much longer for heat to travel to your hardwood, carpet, or tile.
#Radiant floor heating cost estimate install
It is far easier and faster to install Thermalboard on top of the subfloor rather than beneath it. While the aluminum plates may only cost $1 / sq.ft, installing this type of system properly is extremely labor intensive. Underfloor heat transfer systems are often promoted to the DIY market because the components by themselves are relatively cheap. Because the tubes are installed in the floor cavity, wasted heat also travels downward where it remains trapped beneath the subfloor. Heat travels from the tubes and must penetrate first the subfloor layer, and then up through the floor. Underfloor heat transfer systems are installed beneath the subfloor.
