Takagi T-T2-IN-NG Indoor Commercial Condensing Tankless Review
The Takagi T-T2-IN-NG is an indoor commercial condensing tankless water heater. "T-T2" identifies the commercial platform; "IN-NG" means indoor natural gas configuration.
Specs: 199,000 BTU natural gas input, UEF 0.95 condensing, 11.0 GPM at a 35°F rise, dual stainless heat exchanger with commercial-grade reinforcement. PVC condensing venting. 12-year warranty on heat exchanger.
The T-T2 commercial line is positioned for higher cycle counts than residential. Same fundamental engineering as the T-D2 residential platform with reinforced commercial components.
About $2,800 unit, $4,500 installed. Right buyer: light commercial application (small restaurant, salon/spa) or very-large residential where commercial-grade durability matters.
