Working in Weymouth
In Weymouth we cover DT3 and DT4; we also cover Dorchester, 7.2 miles away, and Poole.
In Weymouth, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Weymouth bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. For Weymouth homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of Dorset 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
- 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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- 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.
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.
