Electric underfloor heating systems for wet rooms, convert cold surfaces into warm, safe areas for use, but understanding the installation process is key to the whole project.
Prepare the Subfloor First
Before you start laying the underfloor heating, make sure the subfloor is clean, level and dry. Make sure any bumps or dips in the subfloor are filled to a depth greater than 3mm. This will ensure that the heating mat is not damaged when the floor covering is laid on top of it and then walked upon.
Lay the Insulation Board
A layer of insulation board is laid on top of the under floor heating, normally around 6mm to 10mm thick, depending on the insulation chosen. Insulation stops the heat from the under floor heating, travelling downward, through the structure of the building, and rising up into the room.
Fix the Heating Mat or Cable
Next, the heating mat or loose cable is fixed to the insulation board using adhesive tape or staples. This forms a series of even loops across the area to be heated. Importantly, there must be consistent spacing between each cable or loop of mat to ensure an even warm floor and no cold spots.

Connect the Thermostat and Power Supply
For electric underfloor heating in Gloucestershire for example, the electrical connection to the mains for the thermostat would need to be completed by a registered installer. This is notifiable electrical work therefore would require a Part P registered installer to complete.
Cover the Floor
Self-levelling compound can be poured over the mat to create a level surface for tiles to be laid on top or suitable timber/LVT flooring installed.
Test Before Use
A resistance test is completed to check for any possible damage to the mat. Finally, the electric under floor heating system is powered up to cure the system over a period of several days.
Now you know the process of installing the underfloor heating system and no unexpected surprises await you on the day of the installation.
