Anyone recommend a smallish, cheapish combi boiler?

[Jak]

Thanks. Why does it have to be an unswitched socket?

Because the boiler must be isolated by both poles.

Switched sockets don't comply as many of them are single-pole switched. Therefore an unswitched one must be used, forcing the plug to be withdrawn for isolation, which will isolate both poles.

Simply switching off at the socket is not guaranteed to provide isolation.

I was wondering what (n) meant by 'central heating control wiring'. Surely they can't mean the low-voltage wires going to a room stat, etc?

All the room stats I've seen are wired at mains voltage. Now, technically, that *is* "low voltage", but probably not what you meant...

[John Rumm]

Wiring between room stat, programmer, tank stat, motorised valves etc. Most of which *is* actually mains and not low voltage.

I wonder how you read the "rules" if you have an existing socket and replace it with a FCU to hook the boiler to. Its not adding new wiring just replacing an accessory (which is allowed even in a kitchen)?

[Owain]

It wouldn't be a "like for like" replacement though ;-)
