Verified Reviewer |Combi Boiler Poor Performance
I installed Rinnai M160C combi boiler back in September 2019. Each winter, the boiler turns off giving errors code of filling needed, and dynamic pressure check failed constantly.
The screen display always tells to Reset the boiler that I do all the time. This Rennai boiler system is so unreliable that it turns off in the middle of chilly night and need to reset if that even works.
There is no Rennai customer service that even listen to any customer and provide any guidance. They usually tell the customer to reach out the installer who actually rip you off in all terms. I called the installer who is Rinnai authorized dealer.
The technician did not even know why the unit is behaving like this and changed the pressure sensor and circulator pump which is just 4 years old and charged $2000. This amount is almost the price of new boiler and the fault still persist, but there is nobody in Rinnai to listen and help.
So, please be aware of buying this garbage item and save your hard earned money!!!
- Poor performance
Preferred solution: Full refund

Verified ReviewerFreeze protection/complaint
Was able to get an email address for engineering. They responded promptly but were of little help.
Its in my basement which is always 62. Im on solar so its a big deal to me at night.
I called to ask two things.
Assuming its use is related to outside air temp via the ventat what temp does it turn freeze protection on? And 2, how do I disable it?
Your phone person would not let me talk to a tech and was very unhelpful which reflects very poorly on your business or chance of me or anyone I know ever doing business with you again
