What outlet temperature is ideal in a residential boiler?
I am a fairly clueless homeowner with a Lochinvar Knight WHN155 boiler. Recently I had an issue where the boiler locked out because the outlet temperature increased to 160 F which was set as the automatic shutdown limit. The manual describes how the outlet temperature is used, but... what actually is the outlet temperature? Is there a problem if it is reaching 160 F? It is usually stable at 130 F. I have no idea if this is a "correct" or ideal temperature for the outlet temperature sensor to read and would appreciate any insight. If it is not a healthy temperature, where/how would I adjust it? Thanks for your time.
