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.

Need to replace hot water lines. Do you need to turn off the hot water heater if you shut off the main water line?
Yes. I would. If you are replacing the hot water lines, it is also a good time to drain the hot water heater and get rid of all the junk at the bottom of the hot water heater. That should be done once a year. Your hot water heater must be off when you do that, your hot water heater should be off when you drain your hot water heater. You will see boiler scale come out of your water heater. Leaving the boiler scale in your water heater makes it less efficient. It makes it harder to heat your water. It is the same as throwing money down the drain. If you want to give your money away, you should give it to the Salvation Army instead of the Utility Company.

How does a water heater work?
"A water heater stores water in a tank and heats the water with a flame at the bottom. The hot water rises to the top of the tank, while the colder water falls to the bottom near the heat source."

Is it called a hot water heater or water heater?
It's because "hot-water" is a compound adjective, modifying "heater". It's not for heating water, it's for heating a house with hot water. There are many types of heaters that heat water, but only a hot-water heater is used for providing heated water for domestic use. A hydronic boiler also heats water, but it's only for use in radiators.The name "Hot Water Heater" is completely wrong for any use. There is no need to heat hot water. IT has always been "water heater". The term hot water heater has just been used for years because people don't realize the difference. It has always been WATER HEATER.The first answer is jibberish and makes no practical sense at all.
