Laurentiushaus, Olching (Germany)

Nursing home | 77 sqm | 48 kWth | 2005

Reorganization of the gas central heating installation was necessary, because the new EU-standard was not reached.
Additionally a very high warm water consumption also in the summer was determined. Therefore a CSTS and three mini cogeneration units were installed.
The building itself is in good shape.
