Working in Chesterfield
As well as Chesterfield itself (S40 and S41), we survey in Staveley, Dronfield and Sheffield.
Across a large town like Chesterfield, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. We check door thresholds in Chesterfield homes at the survey, because underfloor heating and new tiles raise the floor slightly. If your Chesterfield home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Supplies across most of Derbyshire are moderately hard. Mid-tone grout and matt tiles hide the odd water mark better than dark grout and high gloss. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A floor sensor set between the heating runs and wired back to the thermostat
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- 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.
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.
