– why can water taps provide very hot water but not very cold water

Question

We can turn our taps to easily provide us with hot water when doing the dishes, but if we want a cold cup of water we need to add ice – why?

Answer 1

Your tap is just a valve, opening a pipe that leads either to the water supply from the mains or to a water heater which is fed from the mains. You have a device which provides a reservoir of heated water which you can open on demand but you don’t have a device which maintains a supply of chilled water to open. Instead there is just water which is room-temperature or whatever the temperature of the ground is (which is surprisingly stable).
