Working in Burgess Hill
We work right across Burgess Hill — RH15 — and in neighbouring Haywards Heath and Lewes.
Homes in and around Burgess Hill vary, so we look at the floor, the walls and the water system before we price anything. Where a Burgess Hill home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. For Burgess Hill homes having the bathroom floor replaced, underfloor heating adds one to two days to the fit.
Supplies across most of West Sussex are 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
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- 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
Decisions to make first
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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.
