Aare Energie AG(a.en<\/a>) and IWB<\/a> are tackling the realisation of a heating network in the Hagmatt border area between the Solothurn municipalities of Olten and Trimbach. The partner companies had made the realisation of the plans for extracting thermal energy from the groundwater dependent on the involvement of Olten Cantonal Hospital. This key customer has now agreed to participate, a.en and IWB announced in a joint press release<\/a>.<\/p>\n

A.en and IWB intend to start construction work on the heating network as early as next year. Its network length is expected to be 6 kilometres. A new heating centre in the Dellen drinking water pumping station is named in the press release as the heart of the system. Two heat pumps, each with an output of around 2.5 megawatts, will extract heat from the groundwater here.<\/p>\n

According to the press release, the provision of heat from groundwater can also be guaranteed at low water temperatures in winter. The annual heat output of the plant is estimated at 20 gigawatt hours. Interested parties who have already requested an indicative offer should now receive concrete offers and be able to conclude contracts. The partners expect the first heat deliveries from 2027.<\/p>\n","protected":false},"excerpt":{"rendered":"
