Dan ignore all conflicting advice and go for a combi. It never ceases
to amaze me that English people love to store hot water in poorly

are easier to install, there is no hot water storage tank and no header
tank in the loft.

What happens when the mains supply fails ? (Which happened to my
village on Christmas Eve)
