Working in Rawmarsh
As well as Rawmarsh itself (S62), we survey in Rotherham, Wath upon Dearne and Mexborough.
Rawmarsh gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For Rawmarsh homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. We check door thresholds in Rawmarsh homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Most of South Yorkshire has moderately hard water. Mid-tone grout and matt tiles hide the odd water mark better than dark grout and high gloss. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A floor sensor set between the heating runs and wired back to the thermostat
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
Decisions to make first
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.
Mat or loose cable
Mats are quickest on square, open floors. Loose cable is easier to route around awkward shapes, pipe boxing and a curved shower area.
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.
