Working in Hemel Hempstead
We work right across Hemel Hempstead — HP1, HP2 and HP3 — and in neighbouring Berkhamsted and St Albans.
Hemel Hempstead has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. Whether your Hemel Hempstead bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room. For Hemel Hempstead homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Water across much of Hertfordshire is 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
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
- A check of the floor construction, the room's heat loss and where the thermostat and supply will go
- A floor sensor set between the heating runs and wired back to the thermostat
- Bringing the system up to temperature gradually once the adhesive and grout have cured
Decisions to make first
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
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.
