Working in Amersham on the Hill
As well as Amersham on the Hill itself (HP5, HP6 and HP7), we survey in Amersham, Chesham and Chalfont St Peter.
Being a smaller town does not change how we work in Amersham on the Hill: free survey, written quote, one team. If your Amersham on the Hill home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. Where a Amersham on the Hill home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric.
Water across much of Buckinghamshire is 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 check of the floor construction, the room's heat loss and where the thermostat and supply will go
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- 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
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.
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.
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.
