Bivalent operation with heat exchanger or 1250 W electric resistance at 230 V. (upon request, a 110V resistance boiler for the US market). High insulation between tank and casing made of expanded polyurethane, in order to maintain water temperature for at least 123 hours. Oversized heat exchanger that provides a practical performance much higher than competing products with double capacity. Can be installed horizontally or vertically. Safety valve set at 4 bar, test pressure at 8 bar. Model A) With enameled glass boiler and aluminum outer coating. Cathodic protection with magnesium anode. Enameled heat exchanger. Model B) With AISI 316 stainless steel boiler and mirror-polished aluminum-like stainless steel outer coating. Stainless steel heat exchanger. Complete with front drain tap. Can be installed on all three axes.
