How to install diy underfloor heating
1. Plan out the position of the heating wires so that the ends are near a convenient power supply. Some systems use a plastic mesh to hold the wires at a regular spacing.
Never try to shorten the matting by cutting the wires.
If you use more than one mat, make sure the sensor on the floor is placed between the two so that it can detect the temperature of both mats.
2. Check the maker’s instructions – mesh systems can normally be cut so that you can fit the wires around the room. Don’t lay the matting under kitchen units and don’t overlap the wiring.
3. The system is supplied with a separate sensor that is wired directly into the thermostat. This must be fitted inside electrical conduit and placed in the floor near to the thermostat position. Chisel a groove to fit the conduit and seal the tip with silicone sealant to stop tile adhesive setting around the sensor.
4. Ask a qualified electrician to check and connect the system to the mains power supply.
5. Spread tile adhesive over the matting and fix your floor tiles. Some systems can also be used under wood and laminate floors, but you may need an insulation board under the element.
6. Refit all the skirting boards and trim any inward opening doors to fit over the new floor level.
DIY Tips
Make sure any concrete screeds and tile adhesive are completely dry before switching on the heating for the first time.
