I am asking as we currently have an ancient Baxi Bermuda back boiler and are
Although a good proportion of modern boiler use sealed systems, and modern boilers are usually more efficient than older ones, it is not the sealed systems bit that makes the difference in efficiency.

OK. There doesn't seem to be data for my exact model, though. Not that it matters - if simply means I'll save more money in running costs. ;-)

Yep. It is obvious to anyone with brains. Now you should say.."thank you Dr Drivel, for your advice and I will go out and buy the Viessmann 333".

Well, no actually. It's not at all obvious. Quite the reverse, really.
If only your qualifications were as true as your name.

Dave, I was trying to make a serious and I thought helpful comment. I understand that you don't want a combi, neither would I.
I was simply trying to point out that if you thought the Viessman was a good choice then the lack of a system boiler option, if that is the case, should not hold you back.

How much saving will depend to a certain extent on how you like tonuse the system. If your existing boiler is room sealed then I'd reckon on you saving about 15% maybe 20%. With a conventional flued boiler you'd save a bit more as there tends to be a greater 'draw' on such flues and the boiler was drag in cold air from outside _into the house_ during operation in winter.

Sorry if you thought that comment was directed at you, Ed, it wasn't.
Trouble is the size of the thing - as expected when it contains an unneeded water store. It's too wide for the cupboard and the height would reduce the 'airing' space considerably. Then there's the cost of paying for the bits I simply don't need.

By the way, I noticed one verse where you mentioned "heat bank" i'd like to know what you meant but I couldn't give a.............................. ......thought to work it out.

I think Ed was referring to a "normal" combi version rather than the storage model. Pricing on that will probably not be much different to a system version anyway, so it can be a way of getting system boiler functionality.
Having said that, their range booklet here:

they do have a good number of system boilers to chose from.

A heat bank is a thermal store using a plate heat exchanger.

..and connect the shower to it giving high mains pressures.
They are now well priced too. What the plantpot wants is a direct modern replacement for the crock he has. He should re-think the system at this stage, always wise, and use mains pressure water all around, hence a one-box thermal store/boiler, giving high flowrates that can be DIYed. Viessmann are not the only makers of these boilers. Vokera and W-B to name a few.
A "direct" replacement? An open vented boiler like the Glow Worm HXi 27 or
28kW (Vaillant inside). S/steel heat exchanger, premix modulating burner. Good and cheap enough. It also modulates down to 5kW. V good, v reliable, v quiet and good parts & service availability. They also do a sealed version as well without the pump inside, last time I looked. The Hxi can also be sealed by fitting the expansion vessel, etc, externally - a later task if need be.- Vote on answer

Which would require extensive plumbing changes that the OP has already stated he does not want.
