Takagi is the tankless subsidiary of AO Smith. Operates with autonomy but inherits AO Smith's distributor network. Compared to Noritz:
Product comparison
| Noritz NRC1111 | Takagi T-H3 | |
|---|---|---|
| BTU | 199.9k | 199.9k |
| GPM | 11.1 | 10.0 |
| Heat exchanger warranty | 12 years | 15 years |
| App | Less developed | Wired controller only |
| Heat exchanger material | ecoTOUGH 316L stainless | Stainless (lighter gauge) |
| Built-in recirc | EZTR series | No (external) |
| Typical price (199 kBTU) | $1,599-1,899 | $1,400-1,700 |
Takagi has longer warranty (15-year) but Noritz has better heat exchanger material and integrated recirc.
App / smart-home
Neither brand has a strong app story. Noritz has aftermarket Wi-Fi options; Takagi is wired-controller-only on most models.
Installer network
- Noritz: Noritz-trained installer network, with strong commercial presence
- Takagi: AO Smith distributor channel — wider plumber network but less tankless-specialized
Commercial
Noritz wins decisively. Takagi has no real commercial cascade equivalent.
When to buy Noritz
- You want the ecoTOUGH heat exchanger longevity
- You want integrated recirculation (EZTR)
- Commercial install
- Heavier-duty residential use (large family, hard water)
When to buy Takagi
- Price-sensitive — Takagi typically $200-400 less than Noritz
- AO Smith / Takagi installer in your area with strong reputation
- You don't need built-in recirculation
Bottom line
Takagi is a legitimate value play if you don't need Noritz's heat-exchanger quality or recirculation features. Otherwise Noritz is the smarter long-term pick.
