Copper coil solar water heater

Copper coil solar water heater, pressurized solar water heater 1. Use the copper coil as the heat exchanger, according with international fashion trend, it is simple to install and use. 2. It takes the advantage of the tap water's pressure. More pressure, more comfortable. 3. It can produce hot water with constant temperature, it is safe and comfortable to use. 4. The water can be heated rapidly, so it can produce the high quality hot water. 5. It can produce more hot water than the general types, much healthier. Pre-heated solar water heater (pressurized solar water heater with copper coil), the characteristic of pressurized solar water heater with copper coilModel NB-140-58/1800-16 NB-155-58/1800-18 SNP-170-58/1800-20 SNP-200-58/1800-24 SNP-250-58/1800-30 Inner tank SS304,Thickness 0.40mm Outer tank Color steel,Thickness 0.4mm Thermal insulation Polyurethane foam,Thickness 55mm Supporting Stand Colorsteel, Thickness 1.20mm Vacuum Tube Ø58-1800,16 pcs Ø58-1800,18 pcs Ø58-1800,20 pcs Ø58-1800,24 pcs Ø58-1800,30 pcs Capacity (Liter) 140 155 170 200 250 Aperture area (m2) 2.18 2.46 2.73 3.29 4.12 Working Pressure (MPa) 0.6
