Can I fit a power shower to this system??

[Phil]

Good mornings,

I'm in the middle of quoting my first Power Shower, the customer has his heart set on a Mira Event XS Thermostatic to replace the old thermo mixer unit.
Its a bungalow, dedicated tank feed hot/cold (proven), good pressure, hot water cylinder and cold water storage cylinder of the correct size (downloaded the instructions), the HTSC is in the next room across the hall from the bathroom, I haven't seen the pipe configuration around the top of the HWSC yet but I'll have a look when I'm there tomorrow.
Basically I've never fitted a power shower before but I've spent the morning researching the installation and as far as I know this shower should work fine, but is there anything I need to be aware of, or anything else I've missed.

don't forget your 3 amp fused spur. needed for shower.

Yep I've accounted for that, to spur off an existing ring main for power shower I need part P - yes??

yes you need part P, do you have part p? if you get stuck let me know and i will come over one evening

Cheers Uug- much appreciated,

I had a look in the airing cupboard and the cold supply from the cold water storage cistern in the loft to the shower is installed in the correct way as per the instructions (to avoid airlock) but its in 15mm.

The hot is 22mm from the copper cylinder to the shower and does not have a surrey flange/fitting.
Should these both be in 22mm for a power shower?, the customer was more than happy with the pressure/temp from the old shower (when it was working!) the old shower was thermoatatic mixer.

Also the pump in a power shower, is it like a central heating pump - an impeller (which moves water around rather than pumps) or does it physically 'suck' water from the tank like a straw??

Thanks for any replys
