Probably the end of the road for this, once you run out of arguments annd start talking like a child.
My point isnt talking like a child because If two people cant cope with using a combi then the country is screwed because there must be 10's of thousands if not 100's of couples that have combi boilers.
But obviously all customers with 2 bathrooms have exactly the same hot water requirements. So let's just ignore them and do what the hell we want to.
