Ive just had my boiler repaired by a qualified chappie , and what went wrong was a build up of black iron oxide , mainly in the 'plate heat exchanger' . Now he said it will probably happen again in time , so recommended a magnaclean unit to be fitted . Having read up on it , I was wondering if i could fit one without having to perform a 'power flush' ? or would you guys recommend flushing the system out aswell? which sounds expensive . My C.H system and boiler is about 20 months old by the way .
Thanks .
Thanks .
