Pump-mixing unit with flow-control valve

To create an autonomous circulation system for underfloor heating or radiator heating, modules consisting of pump–mixing units and manifold groups are used.

Pump–mixing units are designed to provide forced circulation, regulation and maintenance of the required temperature of the heat transfer medium in heating systems. Manifold groups are used to distribute the flow of the working medium to the consumers. They make it possible to adjust and control the flow of the heat transfer medium separately in each circulation circuit.

The efficiency of a heating system based on a manifold group with a pump–mixing unit is ensured by the principle of multiple circulation of the heat transfer medium between the supply and return manifolds with partial extraction and mixing of thermal energy from the high–temperature heat source of the primary circuit. This principle makes it possible to significantly reduce the temperature of the heat transfer medium in the secondary circuits and save 10–20% of thermal energy.
