The inner tank of solar water heater system adopts the 1.2 mm imported SUS304 stainless steel and automatic welding technology which decrease the corrosion.
The Intel and outlet of the solar water heater use the argon welding technology against the 0.8 Mpa pressure. Heat tube conduct the heat energy in the single direction and has some advantages of the quick operation, high heat efficiency and anti-corrosion. It has some advantages of no water in tube, no filthy, no broken tube, anti-freeze, unlimited time of the inputting water and pressure operation. Insulation adopts the polyurethane which has good insulation efficiency. The frame adopts the imported SUS201 stainless steel, which is strong and against the corrosion.
This sollar water heater can be used in extremely cold area since there is no water in the tube.It is anti-freeze.
