“We would like to pinpoint to the existence of a German patent DE 19821256C5 affecting the usage of bivalent 4-way valves in

liquid circulation heating systems. In this patent the usage of a 4-way bivalent valve in a type of heating system isprotected,

in which 2 different heating circuits are operated in parallel, where the return of the first circuit is utilized as heat source for the

parallel second heat circuit. A typical application would be a primary heat circuit with a heat source and a parallel floor heating,

where the floor heating in a regulated manner is heatedthrough its heat source and the return from the primary heat circuit is

utilized as alternative secondary heat source for the floor heating. Such a utilization of our bivalent 4-way valve without approval

of the patent holder is forbidden. All other applications our product group VRB are without restrictions possible.”
