How to Install Underfloor Heating

If you’re upgrading a kitchen, finding some wall space to fit a radiator can be tricky. Thankfully, easy-to-install underfloor heating means you won’t need to. Whilst it may form a part of a wider property development project, in itself it’s a DIY job - you won’t need architects or expert building trade skills, although some confidence in electrical work would be an asset. You’ll need to chisel a channel in the wall to fit some cable, so a little plastering, painting and decorating will be necessary to finish the job off properly.

Remove the skirting boards and plan the underfloor heating layout (heating coils usually come embedded in plastic mesh for convenience these days - all you do is roll it out flat). Taking care to cut only the mesh and not the heating coil, cover the floor area, ensuring you don’t go under kitchen units or overlap the wiring. Position the kit’s thermostatic control on the wall close to floor level, and chisel a vertical channel in the wall beside it to house a conduit - this holds a cable from the floor attached to a sensor which is wired directly into the thermostat. Get a qualified electrician to check your wiring and connect it all up to the mains.

Finally, spread adhesive over the mesh and tile. You might prefer laminate or wood floors, but check the specifications of the underfloor heating system first (you might need to place insulation material beneath the element). Reposition the skirting boards and cut doors to open freely over the new floor level, open the fridge, crack open the sparkling wine, and toast yourself.
