Overview of the NR
The Navien NR is a condensing tankless gas water heater with a 0.96 D.O.E. energy factor. It is Energy Star qualified, with a compact wall mount design which uses much less space than a traditional tank-type water heater. The unit utilizes dual corrosion-resistant stainless steel heat exchangers and can be vented with 3" schedule 40 PVC pipe. The NR uses condensing technology, which is eco-friendly and reduces NOx emissions levels, and allows cascading of up to 16 units in one group within the system. An intelligent remote control has features including touch activate backlight function, built-in recirculation timer for water and energy savings, and advanced water heater diagnosis capability and error feedback.

This heater is the worst idea ever. 5 years of having cold showers, shut downs, having to beat on the unit to get it to come on, one headache after another. I removed the unit to return it it and oh, guess what--now my warranty is void because I uninstalled it. So now I'm out the very high price of purchase. And I've got an 80 pound paper weight. I would suggest not buying one!

As a homeowner (and end user) I canít stand Navien. Their support is awful. We just moved into our house six month ago, and the tankless unit is less than four years old. We realized that it took a long time to get hot water Ė over four minutes! And or house is not very big. In fact, we have one shower right next to the water heater, and it takes over three minutes for that one to get hot. Itís not conducive for washing dishes and baby bottles. And itís wasteful especially when weíre in a drought. We had the annual maintenance done on the unit and the plumber informed us that our recirculation pump was shot. (The pump was shot after only 3 years of being in use). We called our home warranty company and they covered the pump for us, but it took over three weeks for Navien to get us the new pump. I should add that Navien will not speak to home owners directly, only plumbers. So any time something goes wrong with the unit, you have to call a plumber. (My husband and I are both engineers, and he works on pumps and systems at the local nuclear power plant, but Navien wonít troubleshoot the issue with him). Once it was installed, we got hot water right away, for a bit Ė then it quit working. There is an internal or external recirculation mode. We wanted to use the internal mode. (The external mode is great if you have an established routine, you can run it at the same time every day and you get hot water instantly. It basically keeps the water in the line hot all the time). If youíre like us, with sporadic schedules, itís highly inefficient to keep the water in the external line hot all the time). The internal mode essentially heats a small reservoir (about a gallon). That water is always hot, it just takes a few seconds to get to the fixtures. We have had five different plumbers out here. First Navien said that the original plumber didnít flush/bleed the pump, so the second plumber did that. Again the water heater worked for about a day. Then Navien said the entire house needed to be flushed Ė of course everything was fine with the water heater, but there might be debris in the line. So we spent over $500 to flush our system. The water heater worked for a few hours. The water will get hot, but then it wonít stay hot at all. So a shower will use a gallon of hot water, then it goes lukewarm at best. Basically we have a 1 gallon water heater. Then it wonít keep heating the water. Today the plumber came out (6th time) and did the troubleshooting with Navien. Navien recommended using the recirculation pump in the external mode. So we have that set to run all day. It turns on every few minutes Ė Iím no expert but it canít be efficient at all. No one is able to tell us why the water heater wonít work properly with the internal recircation mode. Also, no one will tell us why we canít get hot water if the recirculation pump isnít working or turned on. Before we had anyone fix the pump we could get hot water Ė it just took a really long time.

Do not waste your money on a Navien tankless water heater. I have had my series NR 210 for 3.5 years and it has been nothing but a problem. It breaks down every 4-6 months. Save yourself the frustration and costs and purchase another brand.
