Non-pressurized solar water heaters are all-glass evacuated tubular solardomestic water systems combined with heat pipes inside the glass tube. The solarcollector provides heat through an efficient copper coil. The selective coatingon the inner tube converts solar energy into heat energy and transfers to theheat pipe by an aluminum fin. The liquid in the heat pipe changes into vapor whichrises to the condenser. The heat conducts the water inside the tank and the vaporbecomes liquid, returning to the base of the heat pipe. This continuous circulationtransfers heat from the heat pipe to the cold water in the tank as longas sun is heating the collectors.Features: 1) Vacuum tube: 16 - 32 2) Water tank capacity: 100 - 300L3) Heat insulation layer: 60mm polyurethane foaming, superior heat preservation 4) Inner water tank: stainless steel (food grade SUS304/2B ) 5) Outer water shell: aluminum-zinc steel plate Advantages:-Automatically controlled- Highly efficient insulation with polyurethane
