I have a Wolter 300 water
heater in need of a little electrical
repair. I am aware this manufacturer ceased production some time ago however, the available space dictates the replacement of the unit with one of a similar physical size (400 (h), 300(w) and 100 (d) millimetres or a repair to the existing system.
Firstly, is there a suitable replacement system on the market or secondly is there a circuit diagram for Wolter 300 or a supplier of suitable replacement parts
to affect some repairs
