Our district heating for Jena
Distance heating for Jena - closer than you think
Contrary to what the name „Fernwärme“ might suggest, our environmentally friendly and convenient JenaWärme is produced right here in Jena, in the combined heat and power plant in Winzerla as well as in solar thermal and biogas plants. So very close by, but still far away from your property. The heat reaches you directly via our district heating network, usually in the form of hot water. At the house connection station in the building, the supplied heat is transferred to the house system. There you use the heat for heating and hot water preparation. The cooled water then flows back to the power plant via the closed circuit, where it is reheated.
Whoever relies on district heating benefits from an efficient, environmentally friendly, safe and reliable heat supply. Today and in the future.
District heating expansion Jena
The future of heat supply in Jena is green and climate-neutral. District heating in particular is a key factor in the success of the local heat transition for the supply of tomorrow. That is why we are working specifically on increasing the density of house connections in the existing network and on further expansion.
You want to benefit from the advantages of district heating and use a reliable and secure heat supply? We already offer the option of obtaining district heating in many areas (large areas on the map). In addition, our district heating network will continue to grow over the next few years.Check now using our area map for Jena to see whether a district heating connection is possible at your address today or in the future.

Fernwärme Jena in figures
Because our district heating in Jena is generated almost exclusively using the highly efficient method of combined heat and power generation and renewable energy sources are also used, a particularly low primary energy factor has been determined and confirmed.

Further information on 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.
Jena's path to a climate-neutral district heating supply
District heating will continue to gain in importance in the future, particularly due to current developments and climate policy, when it comes to a comfortable and environmentally friendly heat supply. As part of the climate action plan for the city of Jena and the heat transition, a concrete transformation path towards a green district heating supply has been developed. Step by step, the share of renewable energies in Jena's district heating is to increase significantly - from currently around 2 percent to an expected 91 percent in 2035. The goal of a climate-neutral district heating supply is to be achieved by 2040.
Flow thermal energy
Covers a large part of the heat requirement
The use of the river thermal energy of the Saale is to become the heart of the green district heating in Jena. Almost 50 % of the heat demand could be covered in a climate-neutral way - regardless of the weather - around the clock.
Geothermal energy
contributes to the base load
The existing quartz and red sandstone beds are suitable for generating heat using near-surface geothermal energy. Around 3 % of the heat demand could be covered in this way.
Power-to-Heat
supplements during peak load times
With power-to-heat, green district heating can also be generated from green electricity - especially on sunny and windy days. Electrode boilers, which function like oversized immersion heaters, use the excess electricity to generate hot water.
Hydrogen
replaces natural gas - at least in part
Gas-powered systems continue to make an important contribution to heat generation. For the time being, existing gas boilers will continue to run on natural gas and will gradually be converted to hydrogen by 2040.
Biogas
is gaining in importance
The heat yield of the biogas plant in Jena-Zwätzen, which already generates large amounts of electricity and heat, is to be significantly expanded. In the future, biogas could contribute around 4% to the heat demand - around twice as much as before.
Solar thermal energy
should make a greater contribution
Harnessing the power of the sun and generating emission-free district heating - this option is to be significantly expanded by 2040. For example, it is planned to use areas in the Saale floodplains for the installation of mounted solar thermal modules.
