Working in Hertford
As well as Hertford itself (SG13 and SG14), we survey in Ware, Hoddesdon and Welwyn Garden City.
In Hertford, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Hertford bathroom has a cold tiled floor and no room for a bigger radiator, an electric mat under new tiles is the simplest answer. Where a Hertford home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Supplies across most of Hertfordshire are very 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
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
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.
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.
