Installation example in the external supply shaft
Rooms with water tapping points are usually planned wall to wall. This avoids longer pipe runs and the water piping is closer together.

However, E-module instantaneous water heaters can also be integrated together with other building technology in a supply shaft, which can also be located outside the apartment in the hallway! This makes it easy to carry out maintenance or replace appliances without having to access the apartment.
