Noritz EZTR111 Indoor Condensing Tankless Water Heater with Recirculation
Noritz EZTR111 Indoor Condensing Tankless Water Heater with Recirculation Review
The Noritz EZTR111 is an indoor condensing tankless water heater with integrated recirculation, positioned as Noritz's flagship residential model with built-in recirc — competing directly with Navien's ComfortFlow technology.
Specs: 199,000 BTU input, UEF 0.95 condensing, 11.1 GPM at a 35°F rise, dual stainless steel heat exchanger, built-in recirculation pump with smart-pattern learning. PVC condensing venting. 12-year warranty on heat exchanger, 5-year on parts.
The integrated recirculation pump eliminates the cold-water sandwich at restart — particularly useful for retrofits where adding an external recirculation loop would be expensive. The smart-pattern feature learns household usage and pre-heats the line before peak periods.
Noritz's positioning vs Navien NPE-240A: similar engineering, similar capacity, similar price. Noritz has smaller US service network historically; advantage to Navien in service-density-sensitive markets. The EZTR111 is competitive specifically when local Noritz dealer presence is strong.
About $2,500 unit, $4,300 installed. Right buyer: household wanting tankless with built-in recirc in markets with established Noritz dealer presence.
- On-demand operation at 11.1 GPM — no standby heat loss; unlimited hot water if demand is within flow-rate capacity
- Strong UEF 0.94 efficiency — approximately 20% lower annual operating cost vs 0.62 standard
- 12-year warranty — above-average protection; most competitors offer 6
- High 11.1 GPM output — serves 3+ simultaneous hot-water fixtures in most US climates
- Requires dedicated 200K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
