Pump groups
Pump groups are central components for heat distribution in heating systems and support the orderly integration of heating circuits, storage tanks, and heat generators.
In this category, you will find pump groups for various system concepts – from simple heating circuit groups to mixed system solutions for modern heating and storage technology.

Pump groups for heating systems and heat distribution
Pump groups are important components in water-based heating systems. They support the distribution of heating water between the heat generator, buffer tank, heating circuit, and other system components. Depending on the system design, different versions are used, for example unmixed pump groups, mixed heating circuit groups, or compact system solutions with valves, shut-off devices, and control components.
Advantages of suitable pump groups
- structured integration of heating circuits into the system hydraulics
- clean combination of pump, valves, and connection components
- suitable for new construction, renovation, and expansion of existing heating systems
- clear system layout thanks to pre-assembled or compact assemblies
- suitable selection possible according to heating circuit, connection, system type, and installation situation
Areas of application and target groups
Pump groups are suitable for homeowners, self-builders, HVAC-related buyers, and technically interested end customers who want to integrate heating circuits, storage tanks, or heat generators sensibly into a heating system. Typical areas of application are wood heating, pellet heating, heat pumps, storage systems, mixed heating circuits, and modernization of existing systems. Especially in systems with buffer tanks, multiple heating circuits, or different temperature levels, the correct hydraulic integration is crucial.
Important Selection Criteria
When selecting a pump group, the design, connection size, pump type, mixing function, material, pressure range, temperature range, installation situation, and compatibility with the existing system should be checked. It is also crucial whether an unmixed pump group is sufficient or whether a mixed heating circuit with a mixer and appropriate control is required. Technical data are for orientation only and do not replace proper planning, hydraulic design, or installation by a qualified professional.
For the appropriate system environment, additional categories may be helpful, for example Heating Accessories & System Technology, Control Technology, Boiler Return Temperature Boosting and Fittings.
Frequently asked questions about pump groups
What is a pump group?
A pump group is a compact assembly for heating systems. Depending on the version, it can contain a pump, valves, shut-off devices, thermometers, mixers, or other hydraulic components.
What is a pump group needed for in heating?
A pump group supports heat distribution in the heating system. It connects heating circuits, storage tanks, or heat generators to the system hydraulics and ensures that heating water can be conveyed in a targeted manner.
What is the difference between mixed and unmixed pump groups?
Unmixed pump groups convey heating water directly into a heating circuit. Mixed pump groups additionally have a mixing function to adjust the temperature in the heating circuit as needed.
Which pump group fits my heating system?
That depends on the heating system, heating circuit, temperature requirement, connection size, hydraulics, and control. The selection should be checked based on the technical data and the system planning.
Can a pump group be retrofitted?
In many systems, a pump group can be retrofitted as part of an extension or modernization. Whether this is sensible and technically suitable depends on the existing system configuration.
Should a pump group be installed by a professional?
Yes, pump groups are part of the heating and system hydraulics. Installation, connection, venting, control, and tightness should be professionally planned and checked.
