for cylinders a 210L or 250L one. If the mains cold water flow is poor

you could have a conventional ho****er cylinder, aagin heated by the
heating
loop of the combi.

This requires 500-600 litres of storage for six people showering with
two showers. An unvented cylinder of that size will be well north of
£1000. Two combi's can be bought for far less than the price of one
cylinder alone, which will do a better job never running out of hot
water.

Have you seen the size of 600 litre cylinder? Unvented cylinders
require an annual service.

More figures plucked from the air.

IMM seems to have forgotten about fast recovery cylinders and that the
chances of all six people showering directly one after the other remote.
They're just as likely to get dry and dressed before the next one uses the
shower. And some will prefer to shower in the evening.
