Working in Welwyn Garden City
In Welwyn Garden City we cover AL7 and AL8; we also cover Hatfield, 2.8 miles away, and Hertford.
In Welwyn Garden City, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Welwyn Garden City bath has no shower over it, a thermostatic bar shower, screen and tiling can usually be added in a day or two. If you want a shower in your Welwyn Garden City home that works when the boiler is off, an electric shower is worth considering, as long as the consumer unit can take the circuit.
Most of Hertfordshire has very hard water. If your supply in Welwyn Garden City is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Electrical connection by a qualified electrician, tested and certified
- Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
- A bath screen, tray or enclosure where the shower is new
- New pipework and isolation valves, plus a pump only where the system is gravity-fed from a cold tank
Decisions to make first
Power shower
A mixer with a built-in pump, for tank-fed systems only. It lifts a weak gravity shower but must never be connected to the mains.
Thermostatic mixer
Blends hot and cold from your system and holds the temperature steady when someone runs a tap. The usual choice with a combi or an unvented cylinder.
Rules that apply in England
In England, an electric shower usually needs its own dedicated circuit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, and a new circuit is notifiable under Part P. The Part G limit of 48 °C applies to a new bath in a new dwelling or one created by change of use, not to a shower, but a thermostatic valve gives similar protection. An unvented cylinder fitted to improve the shower must be installed by a G3-qualified installer.
