Takagi T-H1 Tankless Water Heater
Takagi T-H1
The Takagi T-H1 Tankless Water Heater is one of the most efficient water heaters you can buy. That is an impressive statement, but with dual heat exchangers the T-H1 is designed to yield maximum performance. The unit actually uses the first heat exchanger as a preheater unit to recovers wast energy that would go out the vent to preheat incoming water. Condensate from this unit is pretreated internally and discharged via a normal drain line.
Aa a result of the two exchanger design, the heater is extremely efficient (about 92%) and yields a ∆T of 60ºF at a flow rate of 6.1 GPM for inlet temperature of 60ºF or higher. For colder climates, this specification drops to 4.3 GPM. Minimum flow rate is 0.75 GPM for Under ideal conditions, the Takagi T-H1 Tankless Water Heater can deliver over 10 GPM and is intended for either whole-house or other high demand situations. The unit can also supply water up to 182ºF, meeting requirements necessary for sanitary applications needing 180ºF water as a code requirement.
Input BTU ranges from 190-199,000 BTU based on fuel (either LP or NG) and the unit is rated for water input pressures from 15-150 PSI. All input and output connections for both water and gas are 3/4” NPT fittings with a 4" flue. The built in thermostat offers four preset temperature settings: 113, 122, 140, and 182°F. An optional remote temperature control offers 16 presets as well as a high-temperature mode for sanitary requirements.
Safety features include built in freeze protection, a manual reset high-limit switch, a flue backdraft pressure switch, and separate monitoring of all inlet and outlet water temperatures. The Takagi T-H1 Tankless Water Heater is backed by a 10 year heat exchanger, 5 year parts warranty for residential applications. The warranty for commercial applications, however, is 3 years on the heat exchanger and 3 years on parts.
