CU Upgrade and Storage Heaters

[Sherbertlion]

Just a question regarding the best set up for new CU's when storage heaters are still in use.

The existing set up is the standard two Wylex boards, one for storage heaters one for rest of property.

Would you fit two new CU's and also an isolator up front for the whole installation or is there a better way to do it?

Cheers.

You don't say whether the storage heaters are off peak, but if so they will have to be in separate CU, with off peak supply to it

Sorry, yes, they are on E7

A single 4 pole isolator can be used to isolate the whole lot at once.

You can get dual tarrif boards specifically for this, but it is no different to two seperate boards really.

Wow thought this was my next job for a minute!!

I am changing CU with storage heaters on seperate wylex board, not Econ 7 thou, there are two very old looking mechanical timers that the customer wants replacing

Any suggestions what would be a good replacement for the timers anyone???

Not like these by any chance?

If they are sangamo clocks that are in at the moment, then I'd be tempted to leave them.

They are very reliable, and last for years and years and years and years.

If space is at a premium, then you could get a nice little DIN rail monted programmer switching a DIN rail mounted contactor, and fit it all into the CU.

Cheers RF, I think i'll keep these in then and try to source some new covers.

They are currently 3 inches off the ground in the pantry and the blokes misses 'launches' stuff in without a care, how on earth they have remained on the board I've no idea!!

I intend to bring them up about 1.5m where the old fella can reach them without having to get on his hands and knees. 68, bad heart and stands 6feet 3inches tall, ex 'black watch' NO MESSING with him.

He wants a full re-wire but is waiting for the bank to return ALOT of money they have 'miss placed'

The finest timeclocks ever made.

Carlsberg don't make time switches, but if they did....
