In respect to this, how does a gravity heating system work?

Gravity Fed Central Heating Systems When the water is heated it expands becoming less dense and lighter than cold water. The cold water sinks down the return pipe forcing the lighter hot water up the flow pipe and around the radiators.

Likewise, how does a gravity fed water system work? A gravity fed system function thanks to the gravity. It is thus by gravity that the water stored in tank goes down by its own weight inside the pipes and run out from the taps. But this system works only if the pipes and taps are at a lower level than the water level at the starting point.

Regarding this, what is the main principle of gravity circulation of hot water?

The first hot water heating systems were gravity systems. When water is heated, it increases in volume; hence it becomes lighter and rises. Simultaneously cooler, heavier water falls. This is the principle on which gravity circulating systems work.

How does my hot water system work?

An electric water heater works essentially the same way as a gas water heater. It brings cold water in through the dip tube (1) and heats it using the electric heating elements (2) inside of the tank. The hot water rises in the tank and is moved throughout the home through the heat-out pipe (3).
