Description

1) Material of outer tank: SUS****2B stainless steel with 0.*1mm thickness 2)Material of inner tank: SUS****2B stainless steel with 0.5mm thickness3)Including a copper coil4)All glass vacuum tube: ¢*8mm x 1, **0mm5)Heat preservation: polyurethane foam with *5mm thickness6)Support: stainless profiled barThe technology solves the problem that is non-pressure solar water heater is without pressure when the water goes out. The technology avoids the problem of unsteady water temperature existing in the non-pressure solar water heater. Water volume in the tank keeps invariable when use, and it avoids that the heat storage tank is without water. The technology makes consumers keep away from filling the heat storage tank full every day
