The tanks shall be State Water Heaters SID series industrial indirect hot water storage calorifier, model number _SID_xxxx (400-1000L) 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 up to 3 sacrificial magnesium anodes for additional corrosion protection. Entire vessel shall be insulated with 70-100 MM insulation with ABS cladding. Heat loss will meet ErP standards. A combined temperature and pressure relieve valve will be factory supplied. Two factory-installed boiler water/solar heat exchangers will meet the heating requirement as specified for this project. The tank will have the option to install a back-up electric element up to 7.5 kW.
