District heating system of Bolzano
The district heating system was built in 1986 to supply a social housing area. The supply was based on natural gas-powered boilers and a hot water network. In 2006, plans were made to extend the network to a larger part of the city and the nearby hospital and to get a new heat supplier: a waste incineration plant. Through this combination, a larger part of the city could be supplied with district heating while lowering the CO2 emissions. The waste incineration plant was first to be completed and went into trial
operation in 2013 and regular operation in 2014. During this time, the connection to the district heating network was also established, initially as a temporary solution on
the existing connection, and then as a definitive new built connection. In 2016, the expanded Bolzano heating plant with the 5.600 m³ buffer storage and a new, highly efficient (all IE4-drives) pump system became operational. In this new pumping station, the outlets for the three main pipelines (existing city, hospital and industrial zone) have already been realized. This pumping station represents the heart of the Bolzano’s district heating system, here is collected the heat from the incinerator and the heating plant as
well as the buffer storage’s heat and sent on its journey towards the consumers.
