The set is designed to regulate forced water flow in the central heating installation. while maintaining flow proportion control and simultaneous temperature monitoring. The main element of the set is a circulation pump with built-in valves equipped with thermometers to measure the water temperature at the supply and return of the central heating system. The pump group prevents the natural circulation of liquid as a result of temperature differences within the pump group and, among others, the boiler. The set’s casing is made of EPP polypropylene, is characterized by high thermal insulation, light, resistant to mechanical damage, harmless – chemically neutral.
