LOCHINVAR Knight Floor Standing Boiler Reviews

Very Unsatisfied

Michigan winters can be harsh. Decided to "upgrade?" to a higher efficiency model in that our old Weil-McLain Boiler had been good to us, but must have been 50 years old, at best 60% efficient. The old boiler's worst repair was a pump – easy fix, couple hundred bucks – do-it- yourself. I decided on the Lochinvar Knight high efficiency. Bad decision. Problems from the start. Called in the installer several times who advised me to reset, reset, reset,… These new boilers are problematic. Well, he went out of business, so I called Lochinvar to get a "factory authorized" tech's input. He replaced the blower and main valve for $1,400 (this thing was not yet 4). Called the company rep who was extremely rude, saying it was my fault for relying on the installer to get me to reset. I tried to at least get rebuilt spares in exchange for the parts removed – company would not support the boiler. My experience – buy someone else's boiler. This one is headaches.
