Takagi T-KJr2-IN-LP Tankless Water Heater is the smallest water heater in the Takagi tankless line with gas inputs up to 140,000 BTU per hour and an energy factor of 0.81-0.83. This cost-efficient and environmentally friendly Takagi Tankless Water Heater can support hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. Takagi T-KJr2-IN-LP can meet all the hot-water needs of a small American home or apartment with one or two bathrooms.
At an average (rise in temperature) of 60F in warmer areas Takagi T-KJr2-IN-LP Tankless Water Heater will provide 228 GPH (3.8 GPM) and enough hot water for one shower and a lavatory basin at a time; or one low-flow shower (2.5 GPM or less) and an appliance, such as a dishwasher or washing machine, at the same time. In colder areas where the input temperature may be 40F or less you can expect a flow rate of about 174 GPH (2.9 GPM) and running only one major fixture at a time. Please refer to the flow charts for specific rates. The All new Takagi T-KJr2-IN-LP has a max GPM of 6.8GPM.
Takagi Tankless Water Heater T-KJr2-IN has four preset temperatures: 113F, 122F, 131F, 140F.
To achieve any temperatures other than those presets, use the Takagi TK-RE02 remote temperature controller.
To convert the water heater from a standard vent system to a direct‐vent (or sealed combustion) system, use a TK-TV10 Direct‐Vent Conversion Kit. By default (indirect vent), the unit will use the intake air from the room where it is installed.
