I have had a Lochinvar wall mount boiler for 6 years now and it has been a massive headache. I do not know if I simply got a lemon or what the story is but the boiler goes into "lockout" at least 3-4 times per year. What that means is it won't generate hot water until a tech comes to service it. I have done countless manual resets to try to avoid the service call but there is generally a repair needed. I'm at the point where I am considering the option of just replacing the boiler for a new one. Ugh!
"Best boiler ever"
I installed a Lochinvar Knight wbn106 8 years ago. It has worked flawlessly. Never any issues. My fuel bill went down by 50%. It receives a yearly maintenance. An igniter and flame sensor were changed after the 5th year. I would recommend a Knight to anyone who needs an efficient boiler. Another plus is, it is manufactured in USA.
"Cannot say anything but GREAT!"
For my 2 cents, it has been an excellent boiler – six years of zero trouble. It does briefly make a noise as it approaches the lowest firing rate, but that's it. I had to learn a bunch to get the near- boiler piping right, and I can see where a lot of short cuts could have been taken. The old system was so bad I wasn't going to let any of its problems get through into the new install. It has been great, heating the house in 10-20 minutes with 4 zones of fintube, and the 40 gallon indirect hot water heater goes from cold(65deg) to satisfied in about 15 minutes.
"This boiler sucks."
This unit keeps shutting down and locking out. I have replaced igniter, flame sensor, and had technician out dozens of times. It starts working then stops and locks out. It was installed in April 2014.

Hi. I have the Lochinvar Knight WBN106, it is six years old and runs flawlessly. It has yearly maintenance and the heat exchanger cleaned every two years. The outdoor reset has work well. My fuel bill dropped 40% well worth the cost. I would recommend this.
