multiple showers conundrum

[drpop77]

Hi all,
First time on the forum so be gentle!
Ive been asked to come up with a solution to replacing 4 Mira Elite ST showers plus a Gainsboro shower in a student residence. only the Gainsboro runs off the mains, the rest are off tanks and have integral pumps, but keep failing and the landlord is getting a bit fed up.
We have discussed the posibility of boosting the water supply or putting in an unvented cylinder. ive not come across this scenario before and would appreciate some ideas.

unvented cyl with exposed bar mixers?

4 electric showers?

The gravity pumped electric showers are not the most reliable and cost a lot of money. You could fit standard electric showers but would require a really high cold mains pressure that probably wouldn't cope with the demand.

to overcome this a storage tank sized accordingly could be fitted in the loft with a single pump feeding the electric showers.

Doing away with 4 pumped showers and having 1 pump do them all.

A unvented system would be the other option based on the property having the correct water flow and pressure.

But I the system had correct flow pressure to satisfy 4 showers on an unvented setup then you could instead just fit 4 electric showers.

But if the existing tank is big enough just fit a pump ad some elec showers like plumber stated.

Thanks, i reckon im goin to suggest we go down the unvented route as the landlord is keen to get rid of the existing storage tanks in the 3rd storey loft space due to a recent overflow causing internal damage. any idea if i can put a boosted water kit onto an unvented cylinder?

Boosted water kit do you mean a break tank and pump? But the landlord wants to do away with the tank set up.
