Working in Rickmansworth
We work right across Rickmansworth — HA6, WD3 and WD18 — and in neighbouring Watford and Chalfont St Peter.
In Rickmansworth, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Rickmansworth bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Whether your Rickmansworth bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
Most of Hertfordshire 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A floor sensor set between the heating runs and wired back to the thermostat
Decisions to make first
Electric or wet
Electric is cheaper to install and quick to lay in one room. Wet costs more upfront but is usually cheaper to run where it is fed by a gas boiler or heat pump.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
