Lochinvar Knight KBN 399 Heat Exchanger Failure
Had the heat exchanger fail on a Lochinvar Knight KBN399. The heat exchanger started leaking on a cold start up after only three years of service.
Called Lochinvar and was informed that the heat exchanger is covered under warranty.
This was great news as this is one of my best customers.
We next called the supply house wher we purchase Lochinvar products and ordered the heat exchanger. They were very prompt in completing the order and assured me that I would see the part soon.
I next received a call from the supply house informing me that I needed to send a P.O. in the amount of 9000.00 to cover the heat exchanger. I asked why and was informed that while Lochinvar would gladly ship a new heat exchanger, they would need to inspect the failed heat exchanger to determine the cause of he failure. If determined that it was not a defect in manufacture, I would have to pay for the new heat excahnger.
What is the cost of a new boiler, I asked? $8500 was the reply.
I called Leslie Hix , head of the Knight Boiler VIP program since it's inception, and to date she has not the time to return my call. Pretty Arrogant.
I called and talked with the head of the southeast region and was asked to send pictures. After their review, they informed me that the failure was most likely due to refrigerant leaks from nearby chiller equipment and a warranty claim would most likely be denied.
I have never experienced or heard of this in the past. Has anyone ever experienced this?
I have attached pictures of the heat exchanger bottom for those interested in reviewing them.
Very disappointed in Lochinvar. Most of the people I talked to just said that Rules are Rules and there was nothing that could be done.
Take a chance on a heat exchanger that costs more than a new boiler? I don't think so/
