We divided MS Helvetia into three independently controlled heating zones, each with its own room sensor. This allows heat to be regulated according to demand where it is actually needed. In the cooler central area, we added four fan convectors that can quickly deliver substantial heating output to the entrance area, particularly when doors are open. The installation itself was also unusual: bringing in and positioning the new heating system was coordinated with Zürichsee-Schifffahrtsgesellschaft. Supports, fixings and working methods were adapted to the specific requirements of shipbuilding. An unusual request and an unusual job site – which is exactly why this project remains particularly memorable for us.
