Paul,
Thanks for your reply regarding the Economy 7
metering system, it's the same as our Night Rate, over here.
I must say I agree with you regarding wooden floors, noisy they may be, to walk over, but give me wood, any day!.
To coin a phrase from an old Builder friend of mine "It(concrete) just doesn't feel the same, when I comes home drunk and I falls on it".
Back to the subject, Paul, what is the maximum load allowed on an Economy 7 system, in the UK, even if it is switched via a contactor?. [Linked Image]
