Wet Underfloor Heating Systems

Hot Water Underfloor Heating Systems

Installed to run alongside your current central heating system, warm water is circulated through plastic pipes that are installed underneath the floor itself (this can be referred to as the sub floor), which create an ample supply of heat to be transferred through the flooring to whole room above.

Hot Water UFH Systems / Wet UFH Systems on average generate temperatures of 40°C – 65°C meaning that the actual floor temperature will be on average between 23°C – 32°C. This also means that Hot Water Systems heat water to a lower temperature than radiators, which is more economic yet just as efficient for the entire household.

To create a subfloor you will need a professional installation team who have previous experience with Underfloor installations. This procedure may well be expensive so it is normally wise to have the installation completed during a new construction, for example for a new extension, conservatory, open-plan kitchen, etc. A traditional solid floor will be constructed as follows, starting from solid ground you would typically use 100mm compacted stone, red sand to level, visqueen damp course membrane, 75mm foil back solid insulation board, then typically Underfloor Heating Pipes would be fixed to this and finally covered with a 75mm screed. There are various screeds available, again take advice on preparing the sub floor from builder, installer and manufacturer to be sure.

UFH can also be installed in a traditional timber floor system, you would simply lift the floor boards, insulate between the joists, fix metal spreader plates between the joists, run the pipes in the pre-grooved pipe voids within the spreader plate and re-lay the floor boards. The hot pipes then heat the metal spreader plates and create a beautiful uncluttered warm floor above.

A Hot Water System is ideally suited to be installed during a new build construction, however the benefits are so great it may be worth investing in a retro-fit or by using a slimmer overlay system.
