Product Reviews:

My family hasn’t noticed any changes since I made the switch to tankless. The installation was extremely simple, more so than other models I have installed in the past. I’m impressed by the easy to read and access front control and just how quiet the NPE model is; it’s nearly silent.

All Navien water heaters receive very high ratings from consumers. In fact, they are among the highest rated from any water heater manufacturer. Some of the characteristics that are mentioned time and again in reviews include the easy installation, energy savings, solid construction (that is easy to maintain), and small size. Consumers also appreciate that hot water arrives to their faucet in just a few seconds or less and that most models run relatively quietly for gas water heaters. The only complaint about Navien water heaters you’ll find is that they are quite expensive, with an average price of around $1,200. This puts the heaters at the high end of the cost scale. However, with their longer lifespan, greater efficiency (which ultimately leads to cost savings), and top-of-the-range technology, many consumers agree that these heaters are a worthwhile investment.
