Selecting the right district heating substation makes commercial sense

No matter what kind of district heating or cooling substation you need, Danfoss will find a match in our comprehensive range of substations and heat transfer solutions.

Each building has its specific heat demands, every district heating company has its technical connection requirements and each resident have individual heating habits. These criteria influence on the selection of stations for heat distribution in buildings and villages as well as in small and large district heating networks.

The size of a station is determined by the heat demand of the apartment or the building which needs to be heated. Temperature and pressure of the primary power supply determine whether a station is operated directly or indirectly.

In addition, many district heating networks specify special technical connection conditions, which require special control components. And finally, the number and type of heating circuits as well as the form and function of the domestic hot water will influence the needed equipment.

Danfoss offers a complete program of substations and flat stations for ranges starting from 15 kW up to more than 4 MW, for direct or indirect operating mode with one or more heating circuits and primary or secondary side domestic hot water heating as flow, storage tank or anti-legionella system.

The stations can either be pre-defined or pre-ordered custom build solutions. Danfoss has a significant project track record in handling large and small heating and district heating projects, so contact us, and our highly qualified and experienced team will help you to find and dimension the right stations for your requirements.

DSP MOD@ substation
DSP MOD@ substation

DSP stands for ‘Danfoss Substation Prefabricated’, highlighting the fact that you get a substation that is easy to install and that complies with 90% of the typical district heating network technical connection requirements. MOD@ stands for ‘modular and digital’, meaning you get a substation that’s flexible, easy to configure and works seamlessly with our digital district heating network product portfolio.

Direct heating systems
Direct heating systems

Heating systems with directly connected substations are used for decentralized domestic hot water (DHW) production and distribution with a central heat source.

Indirect heating systems
Indirect heating systems

Heating systems with indirectly connected substations are used in networks with low-to-medium supply temperature and buildings with small-to-medium capacity requirements.

Modular or site specific indirect systems
Modular or site specific indirect systems

Modular or site-specific indirect substations are suitable for all networks and buildings with medium-to-high capacity requirements.

Technical information

Around 10 MW appended from temperature program; max. dimension is DN 400.

Please see the available data sheets for substation types DSA, DSP and all DHW products. Or contact your local Danfoss sales office regarding substation types DSE, DSS and DSM to ask for estimation. In case of running order, you will get drawings on request.

Danfoss offers a complete range of DHC substations. Danfoss substations are available in 5 basic platforms, that may be adapted to suit customer needs and requirements:

  • Danfoss DSA - the advanced compact substation
  • Danfoss DSP substation - the compact, pre-engineered and prefabricated heat transfer unit
  • Danfoss DSE substations - tailored to suit the most common customer needs and requirements, configuration based on Danfoss recommendations
  • Danfoss DSS substations - tailored to suit the most common customer needs and requirements, configuration based on Danfoss recommendations; primary media is saturated steam
  • Danfoss DSM substations - direct tailored to suit the most common customer needs and requirements, configuration based on Danfoss recommendations

Circulation water, drinking water, Ethylene-glycol mix and saturated steam.

Yes, in case you have ordered one of our a standard substations with fixed dimensions (see data sheet for DSA, DSP and all DHW products).

For substation types DSE, DSS and DSM, please contact the local Danfoss sales office to receive more information.

It depends on capacity and size/weight. Wall-hanging substations are limited by dimensions and size. We recommend to study the DSA substation types to learn more about our standard solutions.

Yes, it is possible, but not the recommended solution.

E.g. pipe insulation with PU-soft foam, DH boxes from PU-hard foam.

For standard DSA stations there will be insulation cover available in EPP.

Common products are from GRUNDFOS, WILO & KOLMEKS. Other suppliers are possible in special cases. For more information, please contact the local Danfoss sales office.

Case stories

Improved hydronic balancing of the district heating network in Slovenia

The Saleska Valley district heating network is the second largest network in Slovenia, dating back to 1959. Since then, the demands have changed significantly and have challenged the hydronic balancing of the system which was optimized with new intelligent controllers Virtus.

Leanheat makes buildings smart

In Europe, 30 percent of all energy consumption goes to heat or cool buildings. Danfoss has the solution to lower energy usage and improve indoor climate by adding a digital element: Leanheat software.

Successful transition from oil boilers to a local heating network in Eurasburg

In the Wittelsbacher Land near Augsburg the local network in Eurasburg supplies heat to 80 buildings using a wood chip heating system. Danfoss’ substations ensure efficient heating in all building types, and its modern SCADA solution enables remote system monitoring and management. 

Banja Luka
Danfoss partners with the city of Banja Luka to decarbonize district energy

The Challenge: Renovate 34 of the city’s largest heating substations
The Solution: Danfoss Leanheat® Monitor enables full substation digitalization
The Results: reduced heat consumption by 10%

Unlock the grid to its full potential

We can help utilities to optimize their supply of district heating to cities with a positive impact on decarbonization and reduced energy consumption. It's time to unlock the grid's full potential for ultimate cost-effectiveness, energy-efficiency and a resilient path to a greener future.
