Bingo. Last night I BELIEVE I left the hot water tap open in the kitchen
befor going to bed.
About nineti minutes before going to bed I did a load of wash which, I
assume, filled the water heater with cool water.
I'm going to try to get the plumber here tomorrow to fix the leak in the
cold water pipe going to the upstairs bath tub.
