Navion water heater

Navion vs other tankless water heaters. Any body had experience with Navion? Are they as good as the rest, or possibly better or worse. my company just picked up Navion, and i have my concerns, first and foremost, they are very expensive. Any input about tankless water heaters(especially Navion) would be appreciated.

Thanks, Ill keep you posted.

By the way, sorry i mispelled it,,, its actually spelled NAVIEN. Literature says up to 98 percent eff. It is a condensing unit Quite a bit larger than other tankless i have seen, of course the first one i put in was the largest available, so maybe thats is why it was so big. Can be vented with sch 40 Pvc up to 100ft and can also order a model with a built in recircp pump and timer. Quite impressive really, just not sure if it would ever really pay for itself, but the neverending hot water may be worth it to some. the unit i installed can produce up to 7gpm depending on incoming water temp. our water temp is around 47 degrees, so we will get about 6 gpm. Certain models even include a small buff tank that eliminates flow switch meaning you can get hot water with even minimal flow. Check out Navien on the web, they make it sound like the one to beat, but im more interested in actuall info from people that have delt with them and others and can tell me their personall advice. As far as i can tell, navien is fairly new in the game, but sounds like they may be leaps and bounds ahead of some of the others They do have a 15 year heat exhanger warranty and built in leak detection. Sounds a little to good to be true, but like i said, these babys are pricy. My boss did some figuring and figured it could pay for itself in ten years. Thats if you are lucky enough not to have any problems. Maybe if they lasted twenty years, trouble free, then i could justify one, but im afraid there gonna be some service issues, hope im wrong. Lets hear what all you guys out there think.

the pic posting is going good, although i need to learn how to cut a few steps,, thank you again for getting me started.

I was also hoping to hear from Milo on this. We have had our dissagreements about tankless, but now that i will be installing more of them, it would be nice to know if im installing a good product. If they are as good as the saleman makes them sound, Milo, you may even switch over.lol.

the largest unit(without recirc) is around 1800(custermers price, not including labor and materials) With this unit you can run two showers, and one sink and have endless hot water(this will vary depending on ground water temp). if you turn on a fourth(and this is strictly off of my personal findings) it will give you warm, almost hot water, but not hot enough for the average person. But you can run four sinks, and have all the hot water you want. I installed mine in a residential house, where there may be two different showers being used at the same time, but no other fixtures will be in use. So this seems ideal for this household. The unit i installed came preset at 120 degrees. the homeowner was there when i fired it up, and his only complaint was that the water wasnt hot enough. I Kicked it up to 125 and he was happy. I told him to be carefull becuase i noticed that the water actually got hotter after about 30 seconds. It comes with a remote that allows the homeowner to change water temp setting without opening unit. (Crazy??)

This system was installed in a house that has a booster pump, so i really cant trust readings.

My boss is going to install one in his house in the near future, and we will have a lot more time to see how well this thing really works. We are planning on putting it to the test

Thanks afaroo. Great links. Im even more distraught about the prices now. I installed the cr240, our price was around 1500, sold it for 1800. I guess my boss must have some connections, because i dont think he would have taken them on at those prices,, $2344!!, wow. I had to laugh at the utube video. Good stuff, but im pretty sure the guy had no clue as to what he was looking at. Thanks for the info. Much appreciated. I cant get the first one to open(most likely my computer). Thanks again, and, by the way, what do you think of these heaters.
