Air gaps around wiring or piping limit heat transfer and reduce efficiency The floor slab can be preheated effectively Table 01-Hydronic VS Electric Radiant Heating The following are general guidelines for selecting system characteristics: Heating Medium In dry installations, on the other hand, piping and cables are installed in an empty space between floor layers or below the floor, but are not embedded.ĭeciding which heat source and system construction to use is a matter of cost and benefit.It is important to note that “wet installation” is not a literal term: the hot water stays inside hydronic piping, releasing only its heat. In wet installations, hydronic piping or electrical wiring is embedded directly in a concrete floor, or any other solid mass than can hold and emit large amounts of heat.Radiant floor heating systems can also be classified based on their construction: Air-heated installations also exist, but they suffer from a very low efficiency without offering any significant advantages. Most radiant floor heating systems are either hydronic, which rely on hot water piping or electric, which use wiring or conductive mats under the floor. Classification of Radiant Floor Heating Systems Therefore, any improvements to heating performance and efficiency can yield an attractive return on investment. However, but this is compensated by improved comfort and energy efficiency.Īccording to the US Department of Energy, space heating is the highest energy expense in American households, and represents around 45% of energy bills on average.
Radiant floor heating cost to run install#
The upfront cost of radiant floor heating is generally higher than that of other systems, since it is necessary to install hot water piping or electrical wiring under the floor. Radiant floor heating consists on delivering heat through the existing floor surface, as opposed to using air ducts or baseboard heaters.
