What is a Central Heating Wiring Centre?

A wiring centre is a plastic box containing a long electrical connector strip.
The wires going into the wiring centre connect the boiler, hot water cylinder
and the heating controls for the central heating system.

The wiring centre should be in a place which is easily accessible. It is often found in the
airing cupboard. It should have its own fused electrical isolator nearby and this should be
clearly labeled so that the electricity can be easily turned off for maintenance or repair work.

Wires from the wiring centre run to the electrical supply, cylinder thermostat,
room thermostat, programmer, motorized valves, boiler and the central heating pump.
