Description for Takagi T-KJR2-IN-NG

Note: Isolation valves are not included but are recommended for installaltion.

Released in 2010, the T-KJr2-IN & T-KJr2-OS are the smallest water heaters in the Takagi tankless line. This small, but powerful unit can meet all the hot-water needs of a small American home or apartment with one or two bathrooms. Designed to virtually do anything a 40-gallon tank-type water heater can do and more, the compact, wall mounted T-K Jr. can support hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances.

Cost-efficient and environmentally friendly, the T-KJr2-IN can be converted into a direct-vent unit by using the optional TV10 conversion kit for installation in a garage, a utility closet or any confined space in which makeup air may be limited.

Specifications:

  • Capacity: 1 to 2 Bathrooms
  • Flow Rate: Maximum 6.6 GPM
  • Gas Inputs: 19,500 to 140,000 BTU per hour
  • Energy Factor Rating: 0.82
  • Inlet Gas Pressure: Min: 5.0" W.C. / Max 10.5" W.C.
  • Dimensions: 20.3" H x 13.8" W x 6.7" D
  • Direct Vent Capability
  • Electric Ignition

Great little water heater

By Larry

from Point Arena, CA

Verified Buyer

Comments about T-KJr2-IN Takagi Tankless Indoor Water Heater (Propane):

This unit replaced a 20+ year old AquaStar in my garage that had a problematic pilot light. The unit is quiet and smaller than the heater it replaced. When my main house unit quits, I will replace it with another Takagi, and PexSupply will
be where I Look first.

Note: The old 5" double-wall galvanized vent pipe had to be replaced by 4" single wall stainless vent pipe, but I think that any newer unit would require this change.

Comments about T-KJr2-IN Takagi Tankless Indoor Water Heater (Natural Gas):

I had a problem with the first heater it was vibrating and making loud noises I was concerned about replacing it with the same unit but it was under waranty so I returned the old one and installed the same unit again. The new unit worked as it should no noises and seems to run just fine. The real test will come in the fall when the weather turns cool and the need for heat is there

Endless hot water

By John

from Mill Valley, CA

Verified Buyer

Comments about T-KJr2-IN Takagi Tankless Indoor Water Heater (Natural Gas):

Replaced tank hot water heater that was using more energy.
Very easy to install, plug in and you have enough hot water for a hot shower with the washing machine running!
This is a bomb-proof unit that really works.
Pex supply is my source for all radiant needs.

Also bought the indoor version the other half of the house.

Bought this as a heat source for radient floor heat in my garage.These are very high tech heaters,but work very well.It only cycles about 3 hours (once desired heat was obtained)in every 24,so it is very economical.

Is it running?

By ron sjs

from St. Aug. Fla.

Verified Buyer

Comments about T-KJr2-IN Takagi Tankless Indoor Water Heater (Propane):

I am using the unit for household hot water. The time it takes for hot water to reach an outlet appears to be the same as before with a tanked unit.

I wish that temp controller that came with the unit would adjust by degrees not by presets (117- 122-131).

  • T-KJr2-IN Takagi Tankless Indoor Water Heater (Propane)

    Q:

    what about valves for water lines and on hot side for T&P installation?
    Asked on 7/22/2014 by Amen Plumbing & Heating from Rio Rancho, NM

    1 answer

    • CUSTOMER CARE

      A:

      We would recommend part 9007604005, which includes shut-off valves and a pressure relief valve. T-KJr2 units include a high‐temperature shut-off switch, which can serve as temperature relief unless local code requires an external temperature-relief valve.

    Q:

    Can this unit be installed in crawl space and vented through foundation wall?
    Asked on 6/2/2014 by Grizzly Rider from West Virginia

    1 answer

    • CUSTOMER CARE

      A:

      The crawl space would need to be able to supply enough combustion air to the heater, as outlined in the manual. If it cannot, you would need to purchase a direct-vent conversion kit (part TK-TV10) in order to set the unit up to bring in outdoor combustion air. Also make sure that your installation complies with any applicable local codes.

  • T-KJr2-IN Takagi Tankless Indoor Water Heater (Natural Gas)

    Q:

    Please clarify... If I want to convert to direct vent, which products are required? The 3" x 4" Adjustable Concentric Termination OR the Direct Vent Conversion Kit (T-KJr2-IN, T-K4-IN, T-D2-IN) OR BOTH? Thx!
    Asked on 3/1/2014 by Dano from Santa Fe, NM

    1 answer

    • CUSTOMER CARE

      A:

      The direct vent conversion kit is required. It includes parts needed to create an outdoor fresh air intake on the heater and to cover the standard indoor air intake on the front of the unit. Concentric vent terminations would only be required if you wanted to have a single penetration from the building.

      You can, as long as the existing venting is compatible with the T-KJr. unit (which requires 4" Category III stainless steel venting).

    Q:

    The rpecification calls for a 3/4 inch gas inlet. Since we heat primarily ith wood, our propane supply is a 125 gallon tank with 1/2 inch pipeing. The unit will only serve one bathroom, but the well water in the winter is not much above freezing. Will the unit work for this installation?
    Asked on 3/26/2012 by peyster from Bent, NM

    • VERIFIED BUYER

      A:

      Ok. Here is the thing. You need to install a 3/4 pipe from the gas tank to the unit, even if the gas tanks and the unit are 1/2. The more 3/4 pipe are in between, the better the unit will work.!! Very important, otherwise the unit will shut off automatically for error 3. Make sure the unit has its pipe fumes well installed, i mean, it has to have at least 35 inches of vertical pipe and then you can use an elbow.
      And for the water, just make sure the pressure goes up to 20 psi at least..
      With this i think you wont have any trouble..

      A:

      You might get lucky. It depends what other appliances are served by the
      gas line and how far the unit is from the tank. Among other factors.
      If you use 2.5 gpm at 80 degree rise then you will need just about the full
      140,000 BTU rated input for the tk junior.

      I just installed a unit in similar circumstances. 6 months ago.
      no problem with the operation, customer has had consistent hot water.
      We did have a problem with sand from the well.
      make sure that the water supply is well filtered.
      seems like a nice unit

      u must have power (120vac) to operate the onboard computer. if u don't have
      power to your house, u can rig it up with a small converter (available at auto parts or
      building supply store for temporary power.

      No. There is an internal blower and microprocessor that need to be powered up. You could run the unit off of a very small generator though. Power draw is very low.

      A:

      No, a Takagi water heater needs power to vent gasses out of it. If there
      is no power it would be dangerous to try and light it, and I don't think it
      would work.

    Q:

    I currently have a T-Kjr (2006) installed to heat a closed radiant floor system at an elev. of 6,000 ft (near lake tahoe). The heat area is 2,100 sq ft broken into 5 zones. The current unit seems to be having to work to hard for this use. Is there an alternative that would be more effecient, cost effective, and better suited to my needs? I do have sufficent room for a floor based unit or tank type.

    • CUSTOMER CARE

      A:

      For heating a better choice would be a boiler over a water heater or tankless water heater. Boilers are designed for heating where water heaters/tankless water heaters are more designed for plumbing.
