Our district heating for Jena
JenaWärme - closer than you think
Contrary to what the name "long-distance heating" or "district heating" suggests - our environmentally friendly and convenient jenaWärme is produced right here in Jena, namely in the combined heat and power plant in Winzerla as well as in solar thermal and biogas plants. In this way, it's nearby, but, at the same time, far from your property. The heat - usually in the form of hot water - is piped directly to you via our district heating network. With the house service line of a building, the heat provided is transferred to the domestic system. There, you use the heat for heating and hot water. Afterwards, the cooled water flows through the closed circuit back to the power plant, where it is heated again.
Because our district heating in Jena is generated almost exclusively with the highly efficient method of combined heat and power generation and, moreover, renewable energy sources are utilised, a particularly low primary energy factor has been determined and confirmed.

Fernwärme Jena in Zahlen
Weil unsere Fernwärme in Jena fast ausschließlich mit der hocheffizienten Methode der Kraft-Wärme-Kopplung erzeugt wird und zusätzlich erneuerbare Energiequellen eingesetzt werden, wurde ein besonders niedriger Primärenergiefaktor ermittelt und bestätigt.

Here, you can find out more about district heating in Jena
For bringing district heating to the customers, a corresponding network is necessary. Anyone who has their property or house near the district heating network can, in principle, get district heating on request.
The Stadtwerke Energie relies primarily on energy produced by environmentally friendly and convenient combined heat and power (CHP) generation, mainly from the Jena gas and steam turbine combined heat and powerplant of our supplier. In order to drive two steam turbines with connected generators for power generation, the steam produced in the local waste heat boilers is used partly, while the steam from the conventionally operated steam generator is used in full.
District heating is, on the one hand, extracted directly from the waste heat boilers of the gas turbines and, on the other, by controlled extraction from the two steam turbines.
This heat is distributed in Jena by means of a pipeline system with a total length of approx. 226 km. We are constantly modernising the supply network and keeping it up to date with the latest technology. In this way, we guarantee almost 100 per cent security of supply.
We also operate combined heat and power plants (CHP). These plants work on a a "small scale" according to the same principle as large CHP plants, i. e. they generate electricity and heat at the same time. In this way, we can reliably supply whole districts with heat.
