It's also a function of hot copper pipes. Hot water from the water heater heats the pipes to the water temperature as it flows through. If you turn off the source of heat the cold water flowing through the pipes will still absorb some heat from the already warm pipes.That was my theory but it still comes up in my mind every now and then haha
If you live somewhere hot like the North of WA and have water pipes running on the outside of the house your 'cold' water will always be hot to some degree.
