Central heating wiring centre

[iep]

I need a wiring centre to replace an old Randall box that was used in an s-plan CH/HW system. However due to house extension, the replacement needs to be able to support a 2 CH zone and HW system.

Any products out there that are particularly good (or bad so I can avoid them)?

Cheers,

iep

Any standard 10 terminal wiring centre will do the job

Here's the wiring diagram for a 2CH + HW system (know as a S Plan).
