The storage tanks have a sheet steel inner boiler with built-in external current anode, are maintenance-free and have a particularly long service life. For inspection and cleaning purposes, as well as for combination with a finned tube heat exchanger or a flange-mounted heater, these freestanding cylinders are equipped with a 240 mm Ø side flange.
Draining takes place via the cold water pipe. The large-surface heat exchangers enable bivalent or trivalent operation with heating, solar, heat pump or district heating connections.
