NVseries is non-pressurized compact solar water heater, we use patent pipe in tube technology improved the asborbing performance by more than 10 percent than common vacuum tubesThe vacuum tubes trap incident sun rays, and convert it to heat inside the inner tube. Water, now being heated its temperature rises, density changes, and hot water sections rise through the tube to the top of the tank, while cold water from the bottom of tank replaces it in the tube, to start the cycle again. This natural cycling of water driven by temperature difference keeps water hot when stored in an insulated tank

Inner tank: stainless steel SUS304-0.5mm,adops two advanced welding technologies.

Vacuum tube: QB-AL-N/AL-47-1500/58-1800Outer

tank: galvanized steel sheet with surface plastic painting,long life and beautiful

Insulation: polyurethane, fully foamed and density up to 28-32kg/m3

Frame: coated galvanized steel-1.5mm/stainless steel SUS430-1.5mm
