In order to minimize the carbon footprint of its newly projected housing development area, the municipality of Windsbach decided to provide each new home with sustainable heat. Thus, dozens of houses were connected by means of a district heating network. The distributed energy is being provided by an engine that burns renewable biogas to produce both electricity and heat (cogeneration).

In the Windsbach district heating, a fragment of the network’s water is stored in each house to reduce the peak load that has to be provided to each consumer during the morning hours. In addition, a higher-level control system ensures that the otherwise self-sufficient buffers are charged as a precaution when there is otherwise little demand for heat in the grid. This way, the network’s pipe dimensions may be reduced significantly, thus minimizing the heat loss of the overall grid.

Now this may sound like every house needs a complicated mechanical room to accommodate all the pipes, pumps and valves. But in fact, ENERPIPE designed a device for the TEMPO project that combines all the necessary equipment and the storage tank in the dimensions of a normal refrigerator. It is fairly easy to install and takes care of providing comfort and hot water to each home. The heating installer only needs to connect the pipes and electricity.

This is a confidential deliverable in the TEMPO project. However, we will be happy to answer your questions if you are interested in similar solutions. Please contact: Manfred Abt, (
