Shower installation - en suite

LazyPianist

Having an en suite installed at ground level in a 2 storey house. Will also be having a power shower installed upstairs. What's a decent working head for a shower? I reckon I'll have about 0.6 bar; cistern sits in the loft. Will this be enough for the shower in the downstairs en suite? Also, If I have a power shower installed in the en suite, then both power showers must be connected to a breaker and cannot operate simultaneously - I've decided that it might be best to have a thermostatic mixing valve installed in the en suite shower; this will allow both showers to be operated simultaneously. Anyone know any good manufacturers? Another thing I'm concerned about is dead legs in the hot water supply to the en suite - anyone ever experienced these? Presumably there's a minimum length of pipework for hot water supply.

Cheers

Without spending too much for one you could go for a Trevi one or Mira have nice ones out now , if your willing to spend a few quid go for a grohe one , are you fitting a pump to serve this shower .

When you mention dead legs are you worried about legionella disease or are you worried about the length of time it will take for the hot water to come through , if it's the length of time your worried about you could fit a hot return , but it never done in standard sized houses , it's never really a problem , how far away from the hotpress is the shower , is it far of a run of pipe .

Thank you. Yes, I am considering doing that. I'm not sure if that equates to installing a power shower - from a regs point of view (?)

Both!

how far away from the hotpress is the shower , is it far of a run of pipe.

We could tie into the nearest HW tap; that would be about 6-7 metres of Cu pipe (including rises/drops bends). If we were to tie into the hot tank, double that figure (12-14 metres).

If it was me I'd go for an pump in the hotpress with the hot supply taken from a Surrey flange in the cylinder and a cold supply to the pump taken from the storage cistern , then out of the pump run two independent supply's to the shower valve .
The distance you mention is not too much when you have a pump fitted .
Also if the pump is used frequent enough, and your stored hot water is within the recommended temperature you won't have a problem with legionella .

Also it's okay to have a pump along with an electric shower , there is no problem there , you will be powering this from the socket circuit.

I wouldn't go for a 3 bar pump if your cylinder is not big enough to hold the sufficient amount of hot water for a shower as a 3 bar pump will empty a standard cylinder in no time , so you might want to go for a 1.5 bar pump or fit a larger cylinder , it all depends on what budget you have . And how much work would be involved in getting pipes from your hotpress to the shower
