Arrived on site to investigate a propane boiler with intermittent heat. The homeowners previously had another company look at the issue, and they were told the boiler needed to be replaced. The boiler is a 12-year-old Rinnai wall-hung high-efficiency unit. I explained that this model does not have a strong reputation for longevity compared to other wall-hung high-efficiency boilers. The boiler had an E 02 error code ( no flame forming ). I reset the boiler and it fired and ran while I was there. They said that it keeps going out on an error code. I presented options to diagnose the issue and to replace the leaking and corroded expansion tank. The homeowners decided they would prefer to winterize the house for now and plan to replace the boiler next year.
