it depends how hot the water is
If a steel pipe is fitted with a brass tap, it is the brass tap that will get corroded.
i think its because when you turn on the hot water tap the dirt in the tap has gone because the dirt loses the stickiness and hot water gets rids of stickiness
The water is probably frozen in the pipe
Most probably the "sediments" have settles to the bottom and as the hot water is taken off the top of the heater there will be none in the tap water. Hot water will contain less calcium and other impurities (they fall out and become those "sediments" but hot water may also dissolve other compounds from pipes. I use hot tap water in my coffee pot.
