LOCHINVAR Knight Floor Standing Boiler Reviews

"Dependable, affordable product"

5.0 rating
Very Satisfied

I have had this same unit now for over 6 years. This has been the most reliable boiler I have ever owned. It has not had any type of mechanical issues in the length of time I have owned it. The only maintenance it requires is standard maintenance brought by normal use and wear and tear. When I purchase a boiler I am not usually concerned about price, and this boiler is an absolute bang for the buck. I would recommend this boiler system to anyone that is in the market to put in a new system, or replace an existing system. If I were to recommend any brand to anyone, Lochinvar would be at the top of my list. They displayed excellent customer service when I had questions about installation of the unit, as well as guidance as to what needed done in the line of maintaining the unit.

"Bad heat exchanger"

Very Unsatisfied

After 6.5 years the heat exchanger needs to be replaced. I find this to be a very poor result. I do not recommend this boiler.

"My boiler is very efficient. I love it!"

5.0 rating
Very Satisfied

I have owned my Lochinvar boiler for about two years now. I really like how it is a safe source of heating and earth friendly, it produces all natural gas so it does not harm the environment. Plus, it has cleaner results than the other types of boilers that I had past experiences with. I don't have anything I dislike about it. The quality is very good and it lasts long. So far, so good, and I haven't had any repairs done yet! I would most definitely purchase this same brand again and also recommend it to my friends and family. I know that they will enjoy it because a lot of them do not have a natural gas boiler. Out with the old and in with the new! In my opinion, natural gas boilers are a greater choice for anyone who decides to switch it up and experience something different within their home.

We've had nothing but trouble since we had this installed in 2006. We have spent thousands on techs and parts trying to get it to work consistently. The company sent a rep early on, then ignored our calls. We're up in the mountains using this for heating and hot water, and it's incredibly frustrating. Never again. We will never buy a Lochinvar again. Terrible product.

Our kbn210 was installed a few years ago. It's been nothing but reliable since.
