    Sample specification

    The tanks shall be A. O. Smith ITE series industrial Indirect hot water storage calorifier, model number _ITE_xxxx (400-1000L) or an approved equal. The tank shall be for vertical installation. Vessel shall be constructed to European Pressure Directive for minimum 10 bar working pressure. Vessel shall be glass-lined, have sacrificial magnesium anode for additional corrosion protection. Entire vessel shall be insulated with 70-100 MM NEODUL insulation with ABS cladding. Heat loss will meet ErP standards. A combined temperature and pressure relieve valve will be factory supplied. A factory installed boiler water/solar heat exchanger will meet or exceed the heating requirement. The heat exchanger will be able to handle up to 110 °C heating fluid (boiler water or glycol). The tank will have the option to install one or two back-up electric element with automatic temperature control and high temperature cut-off.
