Working in Harpenden

In Harpenden we cover AL5; we also cover St Albans, 4.7 miles away, and Luton.

In Harpenden, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For Harpenden homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit. If your Harpenden home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.

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

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
The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed

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.

Floor heating and towel rail

Underfloor heating warms the room; a towel rail dries towels. Many bathrooms have both, and a dual-fuel rail keeps working in summer when the boiler is off.

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.

Do you cover AL5 in Harpenden?

Is the water hard in Harpenden?

Can underfloor heating go under a bath or shower tray?

No. Electric underfloor heating must not be laid under baths, shower trays, WCs or fixed furniture, because trapped heat can damage the cable and the item above it. It covers the open floor you stand on, and in a wet room it can run under the tiled shower area.
