Endless hot water and whisper-quiet operation
Replaced an old 50-gallon tank with this Navien condensing unit. Wall-mount footprint freed up huge utility room space. Supplies endless hot water for two simultaneous showers and laundry with zero pressure drop.
Our heating engineer had this installed and commissioned in under a day. Digital interface makes adjusting domestic hot water and heating setpoints completely intuitive.
The high 95%+ AFUE condensing efficiency is real. Modulating burner adjusts precisely to demand. Dual stainless steel heat exchangers are commercial quality and resist corrosion.
Matches the description and photos perfectly. Easy setup and works like a charm. Customer service was responsive and helpful when I inquired about tracking details.
