    Sample specification

    The tanks shall be A. O. Smith IT series industrial indirect hot water storage calorifier, model no. _IT_xxxx (300-3000L) or an approved equal. The tank shall be for vertical installation. Vessel shall be constructed to European Pressure Directive for minimum 7 bar working pressure. Vessel shall be glass-lined, have one to three sacrificial magnesium anodes for additional corrosion protection. Entire vessel shall be insulated with 70-100 mm NEODUL insulation with ABS cladding. Heat loss will meet ErP standards. The tank will have the option to install a back-up electric element. A combined temperature and pressure relieve valve will be factory supplied. A factory-installed boiler water/solar heat exchanger will meet the heating requirement.
