Which? figures not mine, referring to different for heating and hot water. However, convinced not to do combi or electric showers now.

Thanks Indus. What is a break tank and what is an "unvented" cylinder?

Thanks Dan. One way or the other I need to have capacity for peak use when full, but more than half the time have minimum need of much hot water so be able to minimize what is pre-heated. Are tmv valves the same as trvs?

Thanks DCawkwell. OK, so the message is clear to steer away from 6 electric showers, and whatever way I need to check flow rates and increase pressure as necessary. If I go for a system then, I like the idea of the tank-in-tank ACV cylinders: probably have two for the 5 showers and then perhaps...

Thanks Calorific. Again, never thought of that, I'll look into it.

Thanks Ian2008. DNO? I never thought it would be that significant. I was considering 10.5 KW electric showers as there would be no hot water running out and just heating at point of use. Realize I would need meaty cable and dedicated large circuit breakers / fuses. However, thanks for reminder...

Thanks Scoobydo123. Will do a check on water pressure and realize I may need a large pressure storage vessel if going the electric shower route. Also reading up on the ACV tank-in-tank options that seem very efficient for a stored water system, if you believe their own website, but the principal...

Combi or system gas boiler? Just bought a large victorian detached repossession and hope to dabble in B&B business. It has an aging gas boiler and two fairly large hot water cylinders, but they have removed 8 of the radiators before being evicted. With peak demand issues in the morning planning...
