We had a Rinnai tankless water heater installed about a month ago; now the hot water occasionally does not work for hours at a time. The local dealer who installed it came out to do an inspection. Long story short, they installed the "wrong unit" (their words).
The guy was using a lot of technical jargon, but as far as I can gather, instead of installing the correct unit they are just going to replace the regulator. He said that this one was only meant for 11 (unspecified units of pressure) and our lines are running at 13 (unspecified units of pressure) or something like that. This is causing the whole system to shut off regularly. This is what he said anyway.
Is just replacing the regulator of a "wrong unit" a common practice? We paid full price for this (which he says is a comparable unit) but my concern is they are just doing a patch job and this could cause problems down the road. I cannot find any information about this online, and I have no idea what the heck is going on. Any advice is greatly appreciated.
