Working in Darwen
We work right across Darwen — BB1, BB2 and BB3 — and in neighbouring Blackburn and Haslingden.
In Darwen, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Where a Darwen home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Darwen home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of Lancashire 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 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- Bringing the system up to temperature gradually once the adhesive and grout have cured
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.
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.
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.
