Lack of support from Navien 10th callback in 14 months
We made thid mistake of installing about 12 Navien ch boilers during 2010 and and 2011. They have been a NIGHTMARE. A 'bad batch' of LP CH boilers where sent to new england in 2011, they had faulty gps switches and combustion chambers resulting in at least 2 dozen call backs for us. In one home we went through THREE boilers in order to get one that did not have this factory defect. Naviens labor pay is next to nothing and they honestly could care less about our troubles. They are disorganized when it comes to call history and never have the correct information, even though you are registered on every call to them.
Fast forward to today. We have a customer who is on her second ch boiler. The internal pressure switch is going haywire and causing the boiler water feed solenoid to open and it over pressurizes the boiler causing the 30 lbs relief to trip. Ok easy enoug, we will get a new one locally.... WRONG no one keeps parts we need to wait until Monday.
Second problem.... the flat plate is feeding water very slowly back into the boiler side of things (this is a combi boiler) so I also said to please send me a new flat plate. They refused, saying unless I see water coming out of the flat plate potable drain at a good clip when the potable side is de pressurized they will not send a new flat plate! I have seen hundreds of tankless coils, flat plates, and indirects have pin holes navien claims my diagnosis does not make sense! I asked to speak to the supervisor which got me nowhere even after I explained to him our constant troubles with this clients home as well as others. They did not even have any records of us ever even changing the 6 month old boiler even though they sent it!
Im sorry dan if this crosses any lines, but I am just so fed up with Navien I had to do something
