Indirect Pressurized solar water heaters are all-glass evacuated tubular solar domestic water systems combined with heat pipes inside the glass tube. The solar collector provides heat through an efficient copper coil. The selective coating on the inner tube converts solar energy into heat energy and transfers to the heat pipe by an aluminum fin. The liquid in the heat pipe changes into vapor which rises to the condenser. The heat conducts the water inside the tank and the vapor
becomes liquid, returning to the base of the heat pipe. This continuous circulation transfers heat from the heat pipe to the cold water in the tank as long as sun is heating the collectors. |
Features:
1) Vacuum tube: 16~32
2) Water tank capacity: 100~300L
3) 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 |
