The BCDHW series hot water storage tanks have the combined flywheel-producer system with fixed heat exchangers inside the flywheel ( depending on the model) and corrugated stainless steel pipe for semi-rapid DHW production. They are all Class A insulated with thick closed-cell rigid polyurethane free of CFCs and non-removable HCFCs with Class B3 fire resistance according to DIN4102. They are available with a single fixed BCDHW1 heat exchanger or two BCDHW2” heat exchangers.
