Working in Chippenham

In Chippenham we cover SN14 and SN15; we also cover Calne, 5.3 miles away, and Melksham.

In Chippenham, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Where a Chippenham home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Chippenham home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

Most of Wiltshire has 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

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
Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit

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.

Insulation board thickness

Thicker boards warm up faster and lose less heat downwards, but raise the floor; the right choice depends on the door threshold and the next room.

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.

Is the water hard in Chippenham?

Is underfloor heating enough to heat a bathroom on its own?

In a well-insulated bathroom with most of the floor open, it often is. In a small room, the bath, WC and furniture cover much of the floor, so the heated area may be too small to be the only heat source. A heated towel rail alongside is the usual answer.
