Nonsense! If you want to know ask,
don't make comments on a subject you
little about.

No point in asking you obviously...

You haven't tried, you think yiou know-it-all.

Many places have a cold main that
will do 20lpm tops, some even less.
With water companies dropping
pressures to control leaks this situation
is likely to get worse rather than better.

Most do not. Next....

Many people have storage
systems that will deliver 30lpm of water at 65
degrees, which mixed with the 20lpm
from the cold gives bath fill rates
of 50lpm.

So two baths at 100 litres/min. That is some cold water main there. Those
are few and far between. Next....

Twice what your multipoint will do
if only it could get the
cold water to it at a suitable rate.

About 27 litres/min hot only. Most home only get 30 litres./min, so it is
well in there. Next....

The Rinnai will outlast the unvented
cylinder and cannot explode causing

Who mentioned an unvented cylinder?

I did. Please read and understand.
I know it is difficult for you.

So you introduced the unvented cylinder
bit just so you could argue with yourself about it?

Making point, and new appliance hitting the UK. Some idiot on this thread
is say a cheapo 100 litre £100n cheap cylinder can do two bathrooms and
power showers and all that. Boy we really get them here.

You should seek help....
