Working in Weston-super-Mare
As well as Weston-super-Mare itself (BS22 and BS23), we survey in Burnham-on-Sea, Clevedon and Nailsea.
Weston-super-Mare has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. For Weston-super-Mare homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Weston-super-Mare bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Supplies across most of Somerset are hard. Hard water leaves white marks on dark grout and gloss tiles, so matt finishes and stain-resistant grout are the practical choice. 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
Decisions to make first
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
