Ystalyfera gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Ystalyfera bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. For Ystalyfera homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Supplies across most of Powys 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A floor sensor set between the heating runs and wired back to the thermostat
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
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 Wales
In Wales, the Welsh Part P also makes a new underfloor heating circuit notifiable, and it covers more bathroom electrical work than the English version. A registered electrician handles the notification.
