Worcester Bosch 30i for a 4 bed house?

A combi or storage combi would alleviate your current problem with running out of hot water when consecutive showers are taken. The problem arises when or if you add another HW outlet in which case you'd need a mains upgrade to fully utilise a storage combi.

Everyone has their own preference
There is no benefit of a combi with the size of your property especially if your looking at running 2 showers at once. Maybe a storage combi made be sufficient but you already have system that could be upgraded (probably less work) to achieve much better results and performance that no combi could match
