    Belgrade's district heating (DH) system is one of the largest in Europe with a total network length of 1420 km and capacity of over 2800 MW. The majority of the network is run on the natural gas boilers and fuel oil boilers with no waste heat from cogeneration or other sources being used and very little renewables (0,75% of capacity). Energy efficiency of the building stock is quite low, and the intensity of energy consumption is high. The city needs harmonized approaches to efficiency.

  • Objective
    Technology

    Heatpump water heaters which use an electric compressor, can produce hot water up to about 90degC for industrial or commercial purposes. Industrial applications include cleansing, thermal disinfection and heating/cooling/air-conditioning in industrial use.Commercial applications include provision of hot water in hotels and hospitals. High efficiency can be achieved when waste heat (e.g. from sewage, industrial wastewater) is utilized and/or when heat and chill energy is extracted simultaneously.

  • Objective

    In addition to improving the efficiency and reducing carbon emissions on the main unit of the boiler itself, it is also important that the unused waste heat is used effectively and that the heat losses from various points are reduced.
    To this end, measures are taken such as heat recovery from the steam condensate after its use in the facility, recovery of the boiler blowdown heat, heat insulation on the steam piping, and action required for steam leaking from traps.
