A typical (gas or electric) tank water heater is simple, just not as efficient. Because this is more complex and newer technology, it has more "failure" points, so don't dream that this will be as reliable as an electric tank water heater. But, it is compact, quick, efficient - so just make sure you get a good extended warranty that includes the labor cost of fixing problems.

This unit works great, I have four of them ranging from 4 years of use to current. You must have enough gas flow to unit at least 3/4 ".Intake and out flow as instructed. I you call Navien in NJ. THEY ARE GREAT in helping you with any issues. If you are not experienced with these units I recommend you fine a plumber that is versed with these boilers. The number is 800-519-8794 , I am engineer so following any repair of this unit will take some good knowledge of it's function.

When a navien is sized and installed correctly it will provide continuous hot water.

I have one that I installed myself a month ago and so far I haven't had any problems. I'm most pleased with the circulation pump. No waiting for hot water.

Return it. Not trying to be sarcastic the only other thing to do is a reset and see if there are any software updates.

My best guess is to contact customer service. Because mine still works very well.

I agree with Eric. I doubt the interface has changed. I suggest buying it from a reputable place where you can return it if not satisfied That way there is little risk to you.

Mine stopped working long before it needed an update. Toss it and buy a Garmen.

I tried that when they sent the new sensors and hub as an update. The system did not work with the new hub and old sensors, so I changed out the sensors, and was good to go.

I really have no idea why. Mine has been working perfectly from the start. Good luck to you.

If you receive a WORKING Philiips unit, if must be one of recent vintage. I received two in rapid succession a couple of years ago, and neither of them worked. So, I can't answer the question.
