Products intro: A copper coil with *2 metres length is installed the tank as the heatexchanger. When the water flow into the cooper coil, it absorbs the heat from the water in the tank, so it can bear much higher pressure, there will be a strong and more comfortant shower. And, without the tank directly transferring, the water is more clean and healthy. 1) Material a) Inner water tank: imported SUS**4 stainless steel b)Outer water tank: galvanized steel alloy or stainless steel c) Bracket: galvanized steel or aluminum alloy 2) Solar vacuum tube a) Size: *8*1, **0mm b) Quantity: *0/ *4/ *0pcs c) Hail resistance: diameter *5mm 3) Temperature insulation layer a) *0mm imported polyurethane, keep same temperature and high pressure foam b) Heat preservation: *2 hours 4) Capacity: **0/ **0/ **0 liters 5) Tank diameter: **0/ **0mm 6) Max. pressure bearing: 0.6Mpa 7) ISO***1/ CE certificate/ EN*****5 8) 3 years&#**9; international responsibility for free repairing or exchange due to original quality problems
