Hi,
Wondering if anyone can give some good insight as I have learned some info from browsing this forum.
Situation – recently moved into a 4 bed detached house. When we purchased it had 3 showers and 4 toilets. We converted one into a utility room but we will in the future (hopefully) have 3 showers again and around 19 radiators (currently have 15).
The house currently has a combi boiler, which obviously means two showers cannot be used at the same time. Kids are young now but as they get older, guests etc we would like a better solution.
Looking online the best solution seems to be an unvested cylinder in the attic.
Currently the combi is in the kitchen cupboard with the gas meter under the stairs. The bathroom is above the kitchen and then attic above that.
Thames water measured outside flow rate at 50l per min and 1.9 bar pressure.
Outside tap is 1.9 bar static pressure and 25l per min. think it dropped to around 1.4bar with a tap on.
Kitchen sink drops to around 12l per min flow
Based on these numbers I am told I would need an accumulator tank along with the cylinder. Which would be some weight in the attic, but apparently joists are good and a platform could be built.
Options would be:
Any other options here?
One plumber suggested a low loss header on the boiler as well, which I am not sure why.
We plan to stay in the house long term ,so I would like the best solution and future proof. Did a full electrical re wire when we moved in as electrics were partly from the 60s. redecorated most parts apart from the bathroom above the kitchen, which will likely take some damage during cylinder install.
Still waiting for some companies to quote me but I was wondering what people thought.
apologies for the essay

Options would be:
- Keep boiler in kitchen and have cylinder + accumulator in attic
- Move the gas meter to the exterior (candent have quoted around 2k for this) and then put both boiler and cylinders in the attic
- Move gas meter to outside, any downside to this other than cost + outlook look. Could maybe increase size of gas pipe here also
- Maybe increase the pipe size between the street and my house? House is 1960s so likely a lead pipe, not sure if the increase flow rates matters..
