Working in East Molesey
As well as East Molesey itself (KT7, KT8 and TW12), we survey in West Molesey, Esher and Surbiton.
East Molesey gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Whether your East Molesey bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. Where a East Molesey home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Water across much of Surrey is hard. 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 floor sensor set between the heating runs and wired back to the thermostat
- 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
