It seems that a boiler with warmstart will be much more

the boiler.

Fine if the flow is adequate. Which isn't the case from combis
when filling a bath. Even the very best - and very expensive
models - will be some 4 times slower to fill a bath than a well
designed storage system. Most much, much more.

And at least for my model, it seems to work. So with that, a
stored hot
water system is no longer useful.

Then it's likely you don't have baths?

I'll butt in here since it's more commonly me that fills the bath so
I'm in a better position than J to comment on the before/after
situation. I would say that it takes *marginally* longer with the new
system to fill the bath than it did before, but only very marginally.

And that is far outweighed (for us, I realise not necessarily for
people with more predictable habits) by the benefits of not having to
make sure there's enough hot water in the first place.
