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.

Navien is made by a manufacturer out of South Korea named Kyung Dung. Does South Korea ever make anything good? There are over priced. Some people like the fact that they can be vented with PVC but its a two pipe system. If you use combustion air, you need to make sure there is enough to avoid negative pressure. Lazy people and cheap people will fall for this. Also they do not make outdoor models. These heaters are notorious for outregous temperature spikes that will burn the person in the shower. They can spike up to 15 degrees. Navien is aware of this. They also have had major issues with there PC boards. They chose to launch these units to beat Noritz's condensing heater and Rinnai's upcoming concentric condensing water heater.
