Another 700 km west of Münchenstein lies Tours in France, between Orléans and the Atlantic coast. In autumn 2012, the first HUBER ThermWin® unit in France will be installed in Tours with its 140,000 residents. An office building of about 2,100 m² area is being erected in the city’s district Saint Pierre des Corps as space to be leased to companies and authorities. The local employment office will be the first to move in. The HUBER ThermWin® system will be used for heating and cooling, like at Winterthur in Switzerland, a previous HUBER project. The French investor made his decision in favour of the HUBER solution after they had visited the HUBER project in Straubing. The operators in Straubing had told them about the high operational reliability of the system and the resulting constant heat transfer.
Applications where heat pumps save energy on sewage treatment plants, support heating plants in housing developments and public facilities, or climatise office buildings, are nothing special. It is however unusual that municipal wastewater is used as an energy source in such applications. Wastewater is an ideal energy source with a high heat capacity and high temperatures during the heating period. Its energy value is outstanding, and the HUBER RoWin Heat Exchanger impressively eliminates the disadvantage that it is contaminated water. Germany and Switzerland were the first to make use of energy from wastewater, now also France is jumping onto the ‘energy-from-wastewater train’. Packed with solutions for the most different applications and profitable cost-saving solutions, it will rapidly gather pace very soon and certainly find many other stations in Europe.
