A typical water heater consists of a storage tank, heating elements or burners, thermostats, valves, and pipes. When you turn on a hot water faucet in your home, cold water enters the tank through a dip tube located at the top. The heating element or burner then heats up the water inside the tank to your desired temperature. Visit: https://goo.gl/maps/wK8mEnC6AntahgVW6
