I've fitted vaillants for over 20 years and apart from the hose issue they had a few years ago, I have had no more than a handful of faults.
All boilers are suceptable to non use, and no checking of inhibitor. As I always use inhibitor and always powerflush every boiler change, maybe that's the reason why so little amount of problems.
Or I might be just lucky!
