Noritz EZTR75 Indoor Condensing Tankless Water Heater with Recirculation
Noritz EZTR75 Indoor Condensing Tankless Water Heater with Recirculation Review
The Noritz EZTR75 is a smaller-capacity tankless from Noritz's recirculation-equipped line. The "EZTR75" reflects ~140K BTU output with integrated recirculation. Sister model to the larger EZTR111 in the recirc-tankless line.
Specs: 140,000 BTU natural gas input, UEF 0.94 condensing, 7.5 GPM at a 35°F rise, stainless steel heat exchanger, built-in recirculation pump with smart-pattern learning. PVC condensing venting. 12-year warranty on heat exchanger.
The 140K BTU class with built-in recirc serves 1-2 bath homes where the cold-water sandwich elimination matters but full 199K BTU capacity isn't needed. Competes directly with Navien NPE-180A at similar capacity and recirc-built-in positioning.
About $2,200 unit, $4,000 installed. Right buyer: 1-2 bath home in markets with established Noritz dealer presence wanting tankless + built-in recirc.
- On-demand operation at 7.5 GPM — no standby heat loss; unlimited hot water if demand is within flow-rate capacity
- Strong UEF 0.93 efficiency — approximately 20% lower annual operating cost vs 0.62 standard
- 12-year warranty — above-average protection; most competitors offer 6
- 7.5 GPM flow rate — sized for 2-bath simultaneous demand in warm-climate installs
- Requires dedicated 180K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
