My Boiler heats the tank in my attic. I am told this is approx (100 litres)When I run a bath, I run out of hot water and the bath only has approx 3" of water in it. The water does not go cold, it just runs dry. This has always happened since I moved in.
Should it run dry? How can I increase my bath water (no more room in attic for a biiger tank)
