In Letchworth Garden City, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. Whether your Letchworth Garden City bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. For Letchworth Garden City homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
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
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- A floor sensor set between the heating runs and wired back to the thermostat
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
Decisions to make first
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.
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.
