    Heating network in Aargau to undergo strategic development

    AEW will take over the Hägglingen Zinsmatten heating network from the municipality of Hägglingen on 1 May, according to a press release. “We are delighted to continue providing reliable heating to the customers of the Hägglingen Zinsmatten heating network and to work together to develop the plant in a sustainable manner,” said Daniel Wernli, Head of Heat Production at AEW.

    The heating network, which has been in operation since 2007, supplies heat to 30 properties. Wood chips are used as the primary energy source. The plant’s wood boiler has an output of 450 kilowatts, and an oil boiler is also available. AEW estimates the average annual energy consumption at around 1,100 megawatt hours.

    With the Hägglingen Zinsmatten heating network, AEW now operates a total of 78 such plants in the canton of Aargau and neighbouring regions. The production capacity is more than 240 gigawatt hours per year, supplying a total of 17,000 households.

  • Spreitenbach expands Neumatt heating network

    Spreitenbach expands Neumatt heating network

    The local citizens’ municipality of Spreitenbach has awarded the contract for the installation of the second boiler for the Neumatt woodchip heating system. According to a media release, the work has started successfully. In the future, additional district heating pipes will be laid for the connection of private properties, which will lead to road breakages and may cause partial traffic obstructions, the statement said. The additional credit of 3 million Swiss francs for the realisation of the second furnace line was approved by the local citizens’ assembly on 22 November 2022.

    The first stage of the Neumatt heating network was realised by Amstutz Holzenergie AG as overall planner and construction manager. The new heating centre in Spreitenbach is centrally located on the communal utility yard next to the Shoppi Tivoli shopping centre. The elongated post-and-beam building offers space for two woodchip boilers with an output of 550 and 1600 kilowatts, according to a statement by the company from Emmen LU. The large technical room contains two buffer storage tanks with a total volume of 57 cubic metres, which cover short-term peak loads and enable continuous operation of the combustion plant.

    The long-distance network was 380 metres long in the first expansion stage. The woodchip heating system has been supplying heat since the beginning of October 2022 and heats the buildings in the vicinity that are already connected, such as the Werkhof itself as well as the Im Brühl retirement home and the new Spreitenbach community centre.

    According to Amstutz Holzenergie, 1800 cubic metres of wood chips from the local forest are needed annually for the heating system. After the complete final expansion, the annual demand will rise to 5400 cubic metres of woodchips. This quantity is also to be covered by wood from the local forests.
