Working in Aberdare
We work right across Aberdare — CF44 — and in neighbouring Rhondda and Merthyr Tydfil.
Homes in and around Aberdare vary, so we look at the floor, the walls and the water system before we price anything. For Aberdare homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Aberdare bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Water across much of Mid Glamorgan is 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
- 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- 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.
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.
