The Wombat heat pipe thermosiphon solar water heater is comprised of four main parts:



Basic Operation

Evacuated tube absorbs sunlight and converts it to usable heat. A vacuum between the two glass layers insulates against heat loss. The heat transfer fin helps to transfer heat to the copper heat pipe, which contains a small amount liquid and becomes steam and transfers the heat from within the evacuated tube to the heat pipe bulb, and then gradually heats up the water inside the tank.
