Navien

My unit leaks excessive amounts of water when we shower. I put 2.

1/2 gallon buckets to catch the water. I empty them twice a week and sometimes more. My tech has come out several times and has determined my unit has a problem. When they call the Naviant tech line, they let me know in plain language that I was stupid to put buckets underneath to catch the 10 gallons of water a week.

My water bill practically doubled, and they said tough luck. Please let me know why a unit would drain out that much water while using. We almost replaced the unit when new because it never worked correctly, and they came back 4 times before it quit running cold out of nowhere. Also, the hot water turns cold when I go from full to half on the nozzle.

You have to turn it back to full and wait for it to get hot again. I can't believe this is normal. Over a month, that is approximately 40 gallons of water wasted, and also the damage to my walls if I don't empty the buckets on time.

Please explain. I'm waiting for your response.

My contractor installed a Navien tankless water heater, and I contacted the manufacturer to identify the correct parts for an upgrade. I asked a few basic questions:

Do I need a circulation pump with your valve to reduce water waste?

Does their valve include a pump?

Do you offer a retrofit pump for my unit?

Tech support could not answer any of these questions and would not escalate the call to someone who could.

I then contacted customer service and was told they do not provide support to consumers only to contractors and referred me to a rep, which isn't helpful as a homeowner.

This level of support is unacceptable. I'm simply trying to purchase the correct equipment, and the company is unwilling or unable to provide even basic guidance. I hope they improve their approach if they intend to succeed in the North American market.

I have a Navien combined unit in my 2-year-old home. What a mistake it was installing this piece of crap.

I wish I had read the BBB reviews before okaying my plumber to install it in my new home. We winter in Arizona and live in northern British Columbia, so a reliable heating system is a must, and Navien is far from reliable. Recently, I had to make a very expensive flight home because the unit quit working. Of course, lucky our son lives in the same town as us and was able to get some heaters plugged in before too much damage was done, but still, the cold had created cracks in the sheetrock.

Thankfully, no frozen pipes, but he said the toilets were slushy, so very close. When I got home, it took me 2 days to get the unit to fire back up after getting the error codes cleared. I talked to Navien to see how I could get the zone control error code from coming back and shutting down the unit. Their response was to turn off the main power switch.

Oh, how *** stupid! They suggested I turn off the unit and walk away at -30. It just shows how out of touch they are, or maybe I should say stupid. So now I'm having to rush home again because this piece of crap stopped working again.

The unit will be coming out and replaced with something reliable, and of course, this will cost me thousands, but well worth it for peace of mind.

So hopefully this review will be seen by many others before making the same mistake. Don’t install Navien; they are junk!

I had a very frustrating experience with Navien, Inc. regarding their water heater warranty and technical support.

Despite my initial hope that their warranty would ensure a quick resolution, the process has been nothing short of a nightmare.

After contacting the company about my malfunctioning water heater, they decided to send replacement parts based on their tech support team's judgment that there were no substantial problems with the device itself. However, after waiting for the replacement parts and having them installed, the water heater still refused to work.

The most infuriating part is that this entire ordeal has dragged on for over 11 days without resolution. Their inability to provide a timely solution highlights the subpar quality of their warranty service. Furthermore, their decision to rely on the contractor's input without thoroughly evaluating the issue themselves has clearly caused unnecessary delays and additional inconvenience.

Upon calling tech support and asking what to do next, I was told they still needed to troubleshoot.

When I expressed frustration, I was bluntly told, "If you like to complain, go ahead and do it." This dismissive attitude was extremely unhelpful and added to my dissatisfaction with their service.

Purchase this brand if you think you won't ever need to deal with tech support or warranty.

Otherwise, we would not recommend this brand at all, based on our experience with a device that we purchased about 2.5 years ago.

I would not recommend this company's water heaters to anyone seeking reliable products and effective technical support. I hope they take this feedback seriously and reevaluate their approach to customer service.

Purchased the NPE-240S2. It did not work once installed, so, I called the number provided.

I was told they could not talk to me only the Plummer who installed the unit.

When he called he was told to remove the top and check a few things, then he was told that it was a sense that was not working, so, they will send a replacement to his company. Once the part arrived, the Plummer installed it. And the tank stared lining water.

Now the holidays got in between so, I had to wait another few days after waiting for two weeks already.

The Plummer was busy with other jobs, and asked, to call customer service and tell them that the unit was not working, and I needed a new one.

I called customer service and explained to them the situation, and all they told me was that they customer not do anything that the Plummer had to talk to the technician, I tried to explain to her that it was going on four weeks with no hot water and that I was loosing a lot if water, the rude lady again said she could not do anything.

I asked to talk to a supervisor, and she said there was no one that could help me, she hung up on me, then I called back to a different department only to get the same response.

After waiting for about an hour I finally spoke to technical support only to say "that maybe the Plummer removed a part.

My thing is and started to think why world they ask the Plummer to move our replacement anything in side the tank?

He's a Plummer, not a tank technician. And according to them now it's the plumbers fault that the tank is not working.
