A building over 200 years old in Hagenbuch (ZH) was converted into a modern two-family home in 2024. State-of-the-art building services were incorporated into the renovation: In addition to a heat pump and a roof-integrated PV system, triple-pane windows were installed. Four Joulia Inline 3P shower channels with integrated turbulators also ensure maximum efficiency in the bathroom area.
