So this morning, yet again, the water is frozen. Two things I don't understand:
1. There was a cold snap a while ago where it was colder than this for a longer period and the water never froze, so why is it freezing now?
2. Doesn't the hot water tank hold a quantity of water? I understand that the cold water which only has a very small header tank inside the house freezes because it's basically coming straight from outside, but shouldn't I have a bathtub full of hot water? Or is there something in the tank that prevents the water dropping below a certain level, so if there isn't fresh cold water coming it, it won't let me take the hot water out?
All answers and suggestions gratefully accepted...
