Hot water cylinder is gone, big leak. Heating engineer is recommending we change the 30 year conventional boiler to a combi and getting rid of the cylinder. We aren't too sure as its a 4 bed house and we have 3 children. I'm liking the idea of a nice big cupboard where the airing cupboard is but we'd of course lose the warm airing part which is needed with the rubbish heat sensor tumble dryers of today.
