Marktredwitz - municipal local heating supply

Haag and Hammerberg are districts of the town of Marktredwitz and are to be supplied with local heating. The area under consideration consists of about 5 existing properties and a planned new development area with about 50 plots and predominantly single-family houses.

The heat is obtained from the waste heat of an existing biogas plant on the outskirts of the village, including a natural gas peak load boiler, and is fed into the pipeline network by the plant operator at the beginning. To distribute the heat, a heating network was constructed with PMR pipes, which are flexible composite pipes with a medium pipe made of plastic. The pipeline network comprises about 2,000 metres and was constructed using a double-pipe system.

    Quantification of heat supply from biogas and peak load boiler
    Pre-dimensioning of the heat pipes
    Determination of network length and expected network losses
    Comparison of the advantages of KMR and PMR pipeline systems in relation to the project
    Calculation of economic efficiency
    Presentation of results
  • Design planning
    Drawing up a design on the basis of the preliminary planning.
    Dimensioning of the local heating network, coordination with third parties
    Cost calculation and preparation of a cost plan

    Participation in the release of security deposits
    Contributing to the systematic compilation of the drawing representation and arithmetical results of the object

We help you to realise your concepts!

We would be happy to advise you on the planning of your heating and accommodation concepts. In doing so, we will also tell you what specific opportunities you have to take advantage of the corresponding subsidy programmes. 

Together with you, we will then also implement the concept.
