SOLARAVEN adopts the highest quality control standard on solar water heater production. That is why we can offer our solar water heater with 10 years warranty to the clients.
Process 1
Water tank material we have stainless steel, which is high anti corrosive performance,304 food grade for normal water quality and stainless steel 316L marine grade for salty water and hard water
Process 2
Inner tank material thickness will be tested to be positive torlerance, non pressure water tank 0.5mm ; pressurized water tank 300L 1.2mm; pressurized water tank 500L 2.0mm
Process 3
Polyurethane foam insulation,to be smooth and evenly, enviromentally,high density, 55mm thickness, keeps lower heat loss, only 5℃ loss in 72 hours.
Process 4
Non welding technology. Our non pressure solar water heater's inner tanks are non welding. It avoids of corossive on the welding joints, especially when water quality is very poor in your place.
Process 5
All water tank should take leakage testing by keeping a high pressure for at least 5 minutes, ensure every water tank is qualified in production.
Process 6
Solar water tank equipped with magnesium anode and electric heating element as backup in case of rainy days. We use high quality electric heating element, incoloy800 alloy material,long life. Magnesium anode will protect water tank, change anode each year will avoid corrosion.
Process 7
All water tanks will have own brand logo and print production serial number to make sure every product could be identified and tracking the status of production.
Process 8
Solar vacuum tube with highest heat efficiency and lowest heat loss. Made of high borosilicate 3.3 glass 1.6mm and 2.0mm thickness, diameter 58mm or 47mm , length 1500mm or 1800mm for option.
Process 9
Flat plate solar collector, laser welding absorber plate with high selective blue titanium coating,95% absorption. gross area 2sqm, 2.5sqm and 3.0sqm for option.
Process 10
Solar water heater stand support: material by solid painted galvanized steel, stainless steel and aluminum alloy for option. All stand frames could be mounted both on flat and pitched rooftop.
