Compared to the previous state of art, the invented tank in question resolves many technical problems. It is a cylindrical tank composed of a square bottom absolutely matching the grids of towers of 2 metres in height placed on roofs for supplying domestic-use water to solar geysers. Advantages: great lid at the centre, four rings for its hanging by a crane, four protuberances 5 for the placing of a water float, four protuberances at the bottom for the placing of several connection fittings, great resistance to pressures, great facility to plumbers; no fastening of the middle part of the tank is required. |
