How Many 10kw Showers?

[ED17]

Last year we rewired a bungalow on a large private estate which caters for mentally ill patients. It had 5 bedrooms each with it's own wet room. The builder wanted a 10kw shower in each wet room but as the incoming sub - main was only 16swa protected by a 60amp fuse we told him no. We ended up with one electric shower and 4 mixers off the combi. The client needed a back up in case of boiler breakdown.

There are six identical bungalows and now the next one is ready for refurbing. The builders had two other contractors in to price the rewires. One's told him that 3 x 10kw showers will be ok and this has made the builder happy.

I've spoken to staff in the original bungalow who inform me that the normal morning routine is for two showers to be used at the same time usually while breakfast is being prepared (with electric oven and hob)

I'm sticking to one shower so it looks like I'll not be getting this one.

My spelling and grammar is awful....That's what you get for leaving school at 13 I suppose lol. My electrics are the bollox though

I can tell you're right up there as a tradesman Lee, do you fancy moving down here to give me a hand ?

I can come and help both of you when the builder gives my work to the other contractor.

Let us know how you get on.

Had the meeting. The other contractor had "assumed" an incoming 100a supply and said that as all 3 showers were unlikely to be used at once it'd be ok!

Builder said he'd prefer electric showers because if they run them off the combi and they used two showers at the same time then the temperature will drop. Told him that if they use two 10kw showers at the same time on a 60a fuse then the place will end up in darkness!

Common sense seems to have prevailed and we got the job.

Good news then mate. You could still have a cylinder off the combi acting as a buffer so two showers could be run and the third being electric.

That's what they're going to do. Just finished a 22 bedroom home on the same site and that's what they installed there. I think the builder just thought he could save some money on plumbing.

I'll put my shower circuit prices up so he doesn't consider it on the next one.
