The vertical, standing enamelled exchanger SGW(S)B Maxi Plus 300 l is designed to heat and store utility water. It is ideal for cooperation with a heat pump and a second additional heating source thanks to the use of two Maxi spiral coils (coiled on two diameters), the upper one (for the heat pump) has an area of up to 2.2 m2, and the lower one (for the second source) 0 .9 m2. Insulation is provided by hard polyurethane foam and soft gray PVC foil. Wet-applied ceramic enamel and two magnesium anodes protect the exchanger and coils against corrosion. The design of the heater allows the installation of an additional heat source in the form of an electric set on the O 180 flange in the inspection hole or on the plug 6/4".
