answer 2 Assume an electric hot water cylinder. The cold water is introduced at the bottom of the cylinder, for upon heating, the hot water will rise to the top. If you put cold water in at the top, this would cool the hot water you had just paid for! The hot water will be taken from the top, for that is where it will be.
In an electric cylinder, there will be an electric heating element about 150 mm from the bottom of the cylinder.
[There will always be dirt and crud in the water supply, and some of this will settle at the bottom of the cylinder. Having the element above this will avoid the crud being disturbed each time the element is turned on.]
In the electrical circuit to the heating element, there will be a thermostat, to set the highest temperature to which the water will go. This is vital for safety, as water too hot can cause scolding.
In addition, the electrical supply authority may only allow you to heat your hot water for certain hours of the day, hours when the demand otherwise is least.
A cylindrical shape is chosen, for engineering strength. This will be thermally insulated, otherwise you will lose too much heat.
