Rinnai boiler corroded in less than two years
Rinnai Q85 wall hung boiler. In less than two years the boiler has corroded around the circulator pump. The aluminum also on the heat exchanger has started to disintegrate. The Rinnai rep is telling me it's because oxygenation, and other people have said it could be electrolysis. Didn't know if anyone else has experienced this or seen this happening to boiler in less than two years.
