Multi Room Wet Underfloor Heating Overlay Kit – High Output UFH
Choose one of our professional underfloor heating overlay kits to heat one multiple rooms. These kits are designed to be installed over an existing floor and can be laid onto any solid level surface including tiles, concrete or wood and do not require additional insulation installed beneath. The high density of the boards allows all types of flooring to be used including tiles, following the “flooring advice” below.
These are rapid response heating kits capable of heating all rooms including conservatories, assuming heat loss calculations have been carried out to ensure adequate performance.
The overlay boards MUST be bonded to the floor using the inclusive floor adhesive and cannot be installed dry as a floating floor. Failure to follow correct installation guidelines can result in very costly mistakes. Please ensure you have read our installation guide before installing this system.
Carpets: lay an equal depth baton around the room perimeter to provide a solid substrate to nail grip rods to. Prime board surface using Mapei Eco Prim Grip then cover with a 5-6mm self levelling screed to provide a flat, level surface.
Engineered wood & laminate: include a moisture barrier over the boards before laying flooring. Cover with our 3mm breathable underlay then lay the flooring as a floating floor. Alternatively if the flooring has to be bonded, prime the board surface, cover with a 5-6mm layer of screed then bond the flooring to the screed using Mapei Ultrabond Eco S955 wood adhesive.

Overlay Kit Installation Overview:
We advise laying a 5mm self levelling screed as the subfloor must be perfectly level before laying the boards. The floor must also be clean and free of any debris to provide a strong key for the adhesive. The adhesive is spread across the floor and each board is bonded to the floor. Wait for the adhesive to cure before walking over the boards. The pipe can then be walked into the pre-formed grooves. Pipe clips are not required to hold pipe in place.
