Working in Newtownards
In Newtownards we cover BT23; we also cover Bangor, 4.8 miles away, and Castlereagh.
Homes in and around Newtownards vary, so we look at the floor, the walls and the water system before we price anything. Where a Newtownards home already has a heat pump, or the heating is being altered, a wet underfloor system is worth comparing with electric. If your Newtownards home has a suspended timber floor, insulation boards under the mat stop heat disappearing into the void below.
Most of County Down is supplied with soft water. Soft water is kind to grout, so mid-tone and darker grouts stay looking fresh. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- For wet systems, pipes in low-profile boards or screed connected to a manifold or single-zone kit, with any boiler work done by a Gas Safe registered engineer
- A dial, programmable or smart thermostat, with the supply RCD protected, tested and certified by a qualified electrician
- Resistance and insulation tests on the mat before, during and after tiling, with the readings recorded
- 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.
Floor finish
Tiles and stone pass heat through well. LVT and vinyl can work, but check the maximum floor temperature the flooring maker allows.
Rules that apply in Northern Ireland
Northern Ireland has no Part P, but the heating circuit should be designed, tested and certified to BS 7671, with RCD protection. Building control is not usually involved unless drainage or structural work is being done alongside it.
