Noritz NRCB199-OD-NG Outdoor Combi Boiler Tankless Water Heater Review
The Noritz NRCB199-OD-NG is an outdoor combi boiler from Noritz. "NRCB" identifies the residential combi line; "199-OD-NG" reflects 199K BTU outdoor configuration natural gas.
Specs: 199,000 BTU natural gas input, AFUE 95% (condensing), 5.4 GPM DHW at a 70°F rise, dual stainless heat exchanger. Sealed direct-vent exterior mounting. 12-year warranty on heat exchanger.
The outdoor combi positioning is unusual — most combis are indoor-only. Right answer for warm-climate homes wanting combi space-heat + DHW with exterior wall mount.
About $8,500-$11,000 installed depending on hydronic system modifications. Right buyer: warm-climate primary residence with hydronic space heat + DHW demand and suitable exterior wall mount location.
