Geothermal Heating System (Miskolc - Hungary)
Miskolc is a city well-known for its heavy industry and, consequently, the quality of the air is low (smog is a serious issue in the city) and CO2 emissions are high. Having the second largest district heating system in Hungary, the municipality needs to improve its energy management and become more environmentally-friendly.
A geothermal heating system was implemented to reduce the dependency on natural gas consumption and the emission of greenhouse gases. The first well (Mályi Well) was drilled in 2010 and the thermal water reserve exceeded the expectations in terms of yield and temperature. The heating system of Avas district was the first to be fed by geothermal energy to supply heat to the households and prefabricated buildings. The geothermal heating plant is managed in terms of temperature, pressure, and volume flow rate, via a central remote surveillance system. The official start of heat supply to the City of Miskolc began in 2013.
In the heating season of 2014/2015, 51.19% of the consumers were supplied by the new geothermal heating system, reducing CO2 emissions by 40 tonnes. The project has been awarded with GeoPower Market’s international prize “Best Heating Project 2013”.
