Working in Staines
We cover every part of Staines, including TW15, TW16, TW17 and 1 more postcode districts, and nearby Egham (2 miles) and Ashford (2.1 miles).
In Staines, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Whether your Staines bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. If your Staines home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of Surrey has hard water. 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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- 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
Decisions to make first
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.
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
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.
