Working in Whitstable
In Whitstable we cover CT5; we also cover Herne Bay, 4.5 miles away, and Canterbury.
Homes in and around Whitstable vary, so we look at the floor, the walls and the water system before we price anything. Where a Whitstable home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Whitstable home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of Kent has very 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 dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A floor sensor set between the heating runs and wired back to the thermostat
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 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.
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.
