A district energy network is extremely flexible and can be used to connect as few as 30-40 houses. This allows cities to grow an existing network as funding, planning and other opportunities become available.
Efficient operation of the district heating network requires that the entire value chain from generation, distribution and usage is designed and maintained to be optimum balance.
Danfoss’ many years of experience can help you with designing the optimal district heating network, whether you are starting from scratch or renovating an existing district energy network.
Optimal network design is key to an economically fit district energy network. Therefore we utilize the network thermo-hydraulic model to avoid over-designing and to verify capacity and impact on the whole network. This means that by installing proper control equipment you can benefit from network balancing and therefore lowering your initial investments. The control components and hydraulic model will also enable ∆T optimization which will ensure system efficiency and reduction of primary energy generation cost, as supply temperature will be optimized, and temperature and flow can be balanced in real time.
In heat production the utilization of various heat sources can be optimized by planning the optimal fuel-mix. District heating technology makes use of a wide variety of energy resources:
Also when it comes to peak energy demand Danfoss can support you with expertise and production simulation to enable smart district energy production and distribution planning. This will secure maximum utilization of heat accumulation in buildings and networks.

The Challenge: Renovate 34 of the city’s largest heating substationsThe Solution: Danfoss Leanheat® Monitor enables full substation digitalizationThe Results: reduced heat consumption by 10%
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.
The world’s largest solar heating plant in Silkeborg, Denmark harnesses energy to heat the homes and workplaces of 40,000 citizens. It supplies 18-20% of the annual heat consumption in the city of Silkeborg, Denmark, which has an ambitious target of CO2 neutrality in heat production by the year 2030.
