working principle of energy storage heater
Thermosyphon solar water heating system, working principle
The thermosiphon principle is used in some solar thermal energy systems when the structure of the pipes allows it. To do this, it is necessary that the path of the heat transfer fluid is at various levels and is not too long. Therefore, the movement of the heat transfer fluid between the solar panels and the hot water tank is carried out solely

How to Turn Up Hot Water Heater | HowStuffWorks
The dip tube feeds cold water from your home''s water lines to the bottom of the tank''s interior, where the water starts to warm up. The heating mechanism — either a burner or an element — stays on until the water reaches temperature. As the water heats, it rises to the top of the tank. The heat-out pipe is located near the top of the tank.

Into the indoor water storage tank, the heat is released and conducted into the water.
