The secret to a water heater s design for separating cold incoming water from hot outgoing water is that it relies on the principle that heat rises to do the hard part. It brings cold water in through the dip tube 1 and heats it using the electric heating elements 2 inside of the tank.
This system is not very efficient so some of the leading brands have come out with the answer in the form of tankless water heaters. To understand the concept of heat pumps imagine a refrigerator working in reverse. They only heat the hot water as demanded reducing water heating costs by up to 60.

It s connected to a cold water supply pipe and has an outgoing hot water pipe or system of pipes that supplies heated water to faucets and appliances.
