Some combi's do CH & DHW simultaneously. If you have teenagers in the

Yes _some_ do, the great majority do not, something you often fail to

Perhaps you could compile a list of those you know of which are able to
provide DHW and CH simultaneously?

Why? are you going to run out and buy one before the shops close?
