Navien NR-240A Condensing Tankless Water Heater with Pump and Buffer Tank, Propane Review

First: the Navien NR-series tankless has only been in service since Oct 2009, so the 2yr+ ownership reviews were done on the CR-series. The CR-series did have issues which were addressed in warranty fixes and massively updated on the NR-series. Second: do your research. I replaced my 17yr old A.O. Smith gas tank with the Navien NR-240A. The NR met my criteria of long warranty, EF, min GPM (zero). It didn't hurt either that I was getting the governments credit either, so I went to energystar.gov to do a lot of research heavy lifting. The "A" model included a small buffer tank (to eliminate the "cold sandwich") and a built in circulation pump. Make sure your plumber (or if you DYI) installs recirculation T's at the longest runs (in my case, master bathroom). Combinded with the built-in circulation pump, this will also eliminate the time it takes to get hot water to your facet (example: from 60sec to 5sec). Do not go with marketing fluff from other manufacturers (such as "market leader", "brand leader", etc...), go with what you need and what your criteria is (EF, GPM, warranty).

20JUN2011 - UPDATE: Instead of commenting on each of the "BAD" reviews - I'm going to generalize based on their issues:
* Again - anyone claiming 2+ yrs ownership, take that to mean they have the "CR" not the "NR".
* Installation/Plumber - the absolute key to these products. If the installer doesn't know what they are doing, you'll not have a good experience. If done correctly, you should not have to wait more than 45s for hot water (even if recirc is off).
* If your installer is decent, you shouldn't be calling Navien direct, you call your installer/plumber to resolve your issue.
* You shouldn't have to "doubled" your piping for recirc ... that's a good salesman to sell you that with this unit.
* If you do have a dedicated recirculation line and it's not working correctly - the installer is an idiot and doesn't know the system.
* I have a SINGLE NR with 4 family members (sometimes 5... 3/4 female ... 2/3 of those ... <15yrs old), 3.3k SF, 3 story conditioned space. You cannot tell me that you needed 2 units unless you have a larger family/home with all the stuff (3 x full bath, 1 half bath, laundry, dishwasher).

The level of satisfaction on the NR-Series comes down to this: INSTALLER - If they "just kinda figured it out", you'll end up with a crappy experience. If they know how to size your unit (incoming water/gas lines, incoming water pressures/gas BTUs, upgrades to services (water/gas), upgrades to meters (usually gas), how Navien recirculation works (even if you life is unpredictable), give you the EXPECTATIONS of the install and performance (and hold THEM accountable)), then you should be good to go. Be an EDUCATED consumer PRIOR to making this decision. I'm not pushing NAVIEN as the end-all ... but rather pushing the TANKLESS technologies ... doing research ... educated decision-making ... expectations ... customer support.
