Working in Truro
In Truro we cover TR1; we also cover Falmouth, 7.7 miles away, and Redruth.
Truro gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If your Truro home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. If your Truro bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer.
Supplies across most of Cornwall are soft. 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 floor sensor set between the heating runs and wired back to the thermostat
- 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
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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.
