Takagi T-KJr2-OS-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.

Includes TK-RE02 Remote Temperature Controller.

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-OS-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-OS-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-OS-LP has a max GPM of 6.8GPM.

Takagi Tankless Water Heater T-KJr2-OS has four preset temperatures: 113F, 122F, 131F, 140F.  

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.

Early indications are promising
The service from pexuniverse was fantastic, the unit arrived approx 36 hours after ordering, in good condition. Opening the packaging, the only concern was that the wire for the control panel was not included (really?) requiring an added trip to the hardware store. Otherwise, installation was a breeze. The unit is installed in a summer camp setting, being used for up to 2 showers running simultaneously. Has not even struggled to keep up with the demand from a flow or temp rise point of view (ground water temp is a constant 42F). Will reserve the right to revisit the review after a couple of seasons, but if this unit performs as well as our Rheem or Palomo units, year after year, at the PexUniverse price, this will be a winner.

Ask a Question
Does this unit come with the Internal Freeze-Protection System or does it have to be ordered separately?
Helpful? Yes No
All the "OS" (outdoor) Takagi series come with a built-in freeze protection. However, it only works when electricity is on. For more details, see page 35 of the manual under the "Literature" tab.
