Working in Ferndown
In Ferndown we cover BH22; we also cover Wimborne Minster, 4 miles away, and Bournemouth.
Being a smaller town does not change how we work in Ferndown: free survey, written quote, one team. If your Ferndown home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below. We check door thresholds in Ferndown homes at the survey, because underfloor heating and new tiles raise the floor slightly.
Supplies across most of Dorset 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 floor sensor set between the heating runs and wired back to the thermostat
- The electric mat or cable laid to the open floor, kept clear of where the WC, bath and fixed furniture will sit
- Insulation boards over the subfloor, so heat goes up into the tiles rather than down into the joists or screed
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.
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.
