Hello,
I am looking into upgrading various parts of my residential block's heating and hot water system, which serves 12 flats that resulted from the conversion of two adjacent terraced houses. Our current hot water cylinder has 1000 lts capacity, is vented, is heated indirectly through a gas boiler, and is of the copper variety with an ill-fitting insulation blanket slapped around it.
I would greatly appreciate some feedback on the following:
If we were to upgrade our cylinder, would any of the modern versions make any difference in terms of energy efficiency?
What make would you recommend? There are not many manufacturers that make large capacity indirectly-heated vented cylinders. So far, I have found Hamworthy’s two models: Halstock (stainless steel) and Powerstock (glass-lined).

I will own my flat in this building for a while, and thus I would rather the building buys something of good quality.
The current capacity of 1000 litres has been fine so far. From your experience, do you think we could do with a smaller size? Eg. 700 or 800 litres? The 12 flats comprise of 2 small studios and 10 two-bed flats. It is high unlikely more than 20 people would be taking a shower within the same hour. Assuming 35 litres per shower, that would be 700 litres for 20 people.
Many thanks,
Constantine
