150L Homemade Compact Low Pressurized Pre Heated Solar Water heater for Bathing

Specification:

Working principle of pre-heat solar water heater:

1. The high quality vacuum tubes absorb the solar ultraviolet ray and visible light; then heat the cold

water in the vacuum tube.
2. The hot water rise in the top of the water tank, and the cold water sink to bottom then heat

by solar collector. So the whole system is always circulating continuously. The water we use that

is in the copper coil, not in the water tank, the tap water connect to the copper coil directly, the hot

water in the water tank exchange the heat with the tap water in the copper coil
3. The Assistant water tank can perform the water supply automatically, the water in the tank is

not sufficient, the electromagnetism valve will open its valve, the tap water flow in the water tank,

if the water is full, it will close the valve automatically
4. The whole system can endure high pressure according to the pressure-bearing technology
