Working in Westhoughton
As well as Westhoughton itself (BL5), we survey in Atherton, Hindley and Tyldesley.
In Westhoughton, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Westhoughton bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. If your Westhoughton home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of Greater Manchester is supplied with soft water. 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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
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.
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.
