Which towns do we cover in County Armagh?
Most of County Armagh 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. Whether your Craigavon bathroom is a small en-suite or a large main bathroom, the mat is sized to the open floor, not the whole room.
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
- Bringing the system up to temperature gradually once the adhesive and grout have cured
- 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
- 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
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.
Thermostat
A simple dial thermostat, a programmable one with set times, or a smart thermostat you can control from your phone.
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.
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.
Rules that apply in Northern Ireland
Electric underfloor heating in a bathroom must be on a circuit with 30 mA RCD protection under BS 7671, and the thermostat is positioned to suit the bathroom zones. There is no separate approval for the heating itself, but it should have its own thermostat and timer so it only runs when needed, and the electrical work must meet BS 7671 — in England and Wales it is notifiable as bathroom electrical work. Any work on a gas boiler for a wet system must be done by a Gas Safe registered engineer.
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.
