Buderus S120 indirect

In my own home s120 installed for 10 years . I seem to not have as much hot water . Showers are were you notice it. Any help ? Was going to open up the oberservation port and see if the coils are calcium caked. Any other ideas. Also would you if need be replace it with another indirect. It has been troublefree as has the buderus boiler.

    I tried one of these as a replacement indirect years back, and it never did what it was supposed to. After going thru the rep visit, etc, ripped it out. Wasn't impressed

    Get a HTP Super Store. The coil is self cleanning.

    Maybe the dip tube is falling apart

    A 120 is quite small, you really can't get lots of hot water anyway
