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.
The Challenge:
Find a sustainable alternative to outdated oil-heated boilers
In 2018, the rural town of Eurasburg, Germany needed a heating solution for the extension to the town’s daycare center. At the same time, many homeowners were looking to replace their aging oil-heated boilers. Everyone was interested in getting a renewable energy solution that could take advantage of the town’s abundant natural resource – the Eurasburger Forest.
So, the city council decided to build a local heating network with a central wood chip system, sourcing wood from the surrounding forest. The project was approved on one condition: that the town could connect all public buildings in the community to the new heating network.
The Solution:
Danfoss VXe substations and Leanheat Monitor® power a centralized wood chip heating network
Michael Gail, the heating engineer responsible for the project, worked with Danfoss to choose the appropriate substation solutions for each building. They selected VXe solo stations for buildings with a heating load of up to 30 kW, and DSA1 mini stations for larger buildings with a heating load of 30 to 100 kW. For a heating load of more than 100 kW, they implemented individual, freely planned stations. High-quality microplate heat exchangers ensure an effective heat transfer in all installed substations. The stations also handle the network’s hydraulic balancing, using built-in independent volume flow controllers with integrated motor control valves.
But substations and controllers were not the only reason why Michael Gail chose Danfoss.
The result:
The Eurasburg local heating network currently supplies heating for 80 buildings, including the primary school, multi-purpose hall, fire station, town hall and daycare center. System utilization is currently around 90 percent, which means there’s still room for expansion. They are also considering adding a solar system in the future.
Other rural communities in the region have followed the project closely and are already planning similar projects. Martin Gail explains
He is certain that the Eurasburg local heating network will not be the last his company implements – and he has already selected the partner for substations and SCADA solution: “We will definitely implement our next heating network with Danfoss.”
