High Quality Solar Water Heater with Coil Copper For Home Using

                                  solar water heater with copper coil

Non-pressurized solar water heater of all-glass vacuum tube intergraded with storgetank, are ideal for use in houses and other applications where cheap,reliable hot water supply is required,they are simple,economic and practical.As the specific gravities of hot water and cold water are different,cold water goes downward and hot water goes upward,when cold water in vacuum tubes is heated,it becomes lighter and goes to the water tank,while cold water in the tank goes down to the vacuum tubes,through this circulation,the cold water in water tank will be gradually heated.

1) This tube adopts magnetron sputtering coating technology

2)  Structure: All glass coaxial dual tubes

3)  Material: High borosilicate glass 3.3

4)  Coating: Cu/Ss-Aln/Aln high efficient selective absorptive coating and vacuum heat insulation could get higher heat and have high performance of absorptance and low reflection ratio and performing a strong heating ability.

5)   Vacuum pressure:5×10-4 Pa.

6)   Usage life: more than 15 years.

Material of storage tank

Outer tank: 0.31mm thick galvanized/colorful steel

Inner Tank: 0.31mm thick SUS-304B food grade 

thick Insulation  55 mm thick Polyurethane foam
