The EZTR series is Noritz's premium residential line — built-in recirculation pump inside the cabinet, designed specifically as a tank-replacement retrofit for homes that want recirculation without an external pump installation. Direct competitor to Rinnai Sensei RX and Navien NPE-A2.

| EZTR111 | 199,900 | 11.1 | 75-gallon tank, 3-4 bathroom |

What the built-in pump does
- Eliminates external Grundfos install — pump is inside the cabinet, wired internally, controlled via the unit's controller
- Simplifies retrofit plumbing — connect a return line from the farthest fixture; that's it
- Single warranty contact point — pump is covered under Noritz's 5-year parts warranty
- Schedule-based recirculation — set time windows via the controller
EZTR vs the alternatives
| Noritz EZTR | Rinnai Sensei RX | Navien NPE-A2 | |
|---|---|---|---|
| Built-in pump | Yes | Yes | Yes |
| Buffer tank (cold-sandwich fix) | No | No | Yes (0.5 gal) |
| Learning recirculation | No (schedule only) | Yes (Circ-Logic) | HotButton on-demand |
| Compact small-home option | Yes (EZTR40) | No (smallest is RX130) | No (smallest is NPE-150S2) |
| Warranty (heat exchanger) | 12 years | 15 years | 15 years |

The EZTR40 is the unique product in the category — purpose-built for tank-replacement in single-bathroom homes that want recirculation. Neither Rinnai nor Navien has an equivalent at this size.
When EZTR wins
- Tank-replacement retrofit where you want recirculation
- Single-bathroom homes (EZTR40 — unique offering)
- You don't need buffer-tank cold-sandwich elimination (most homes)
- You prefer schedule-based control over learning-mode
When NPE-A2 wins instead
- Cold-sandwich is your specific complaint — the buffer tank fixes it
- You don't have a dedicated return line (NPE-A2's HotButton works without one)
When Sensei RX wins instead
- You want the most mature learning-mode recirculation (Circ-Logic)
- You want the longest warranty (15-year)
- You have a Rinnai-trained installer nearby
Warranty
12 years heat exchanger / 5 years parts / 1 year labor. See warranty hub.

Bottom line
EZTR is the right Noritz pick for any home where recirculation matters. The EZTR40 in particular is the only compact-tankless-with-recirc on the market — uniquely suited for 1-bath retrofits. For 2-3 bath homes, EZTR75 is the volume pick.
