In Plymstock we cover PL9; we also cover Plymouth, 2.4 miles away, and Saltash.
Being a smaller town does not change how we work in Plymstock: free survey, written quote, one team. If your Plymstock bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. For Plymstock homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Supplies across most of Devon are soft. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- A floor sensor set between the heating runs and wired back to the thermostat
Decisions to make first
Insulation board thickness
Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.
Floor heating and towel rail
Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.
Rules that apply in England
In England, a new circuit for underfloor heating is notifiable under Part P, and so is connecting it to an existing circuit in a room with a bath or shower. The electrician either self-certifies through a competent person scheme or the work is notified to building control.
