Radiant Heat Retrofits

In-floor hydronic radiant heating systems function most effectively when PEX tubing is embedded in the slab of a building. Since this is only possible in new-construction applications, PexSupply.com offers several options for retrofit jobs. Use Uponor’s PEX Rails to attach tubing prior to a concrete overpour. Uponor’s Quik Trak panels also go above slabs or subfloors. 

Below-subfloor options exist for upper floors in new and retrofit projects. In suspended-pipe installations, PEX tubing hangs in the joist cavity. Ultra-Fin plates enhance the efficiency of suspended-pipe systems. Stapling PEX directly to the bottom of the subfloor without any heat transfer plates is not usually recommended. Heat transfer plates, such as Uponor’s Joist Trak, provide more even surface temperatures.
