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

Excellent performance and value

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

I have this unit installed as primary heat source for radiant heat in my shop. This unit started up easily and is working perfectly. No complaints at all.
I did install a condensate trap in the exhaust vent even though this is not a condensing boiler. I would definitely recommend that in colder climates because I do get condensate draining from mine.

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

I live in an RV and this unit works great, even running off a 5 Gal. propane tank, you just have to make sure you have the wright regulator to supply the unit with enough gas. It is quiet, and gets the water really hot. I have not had such a good shower in three years. Thank You for selling this unit for the lowest price I could find.

Terrific Heater

By Raccoons

from Lisbon, OH

Verified Buyer

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

This water heater has replaced my 22 year old Aqua Star. What I like about it: it is quieter since the fan is inside the unit instead of an add-on; it does not have a pilot light; best of all, the temperature is set to the temperature I want and it stays constant and does not need to be mixed with the cold water. I have been using it for 2 months and so far have not a single complaint about it.

Great Product & Fast shipping

By Chris

Verified Reviewer

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

Great Product With Free Remote Controller and very fast shipping. You Just can't beat this deal.

This product is also on Amazon Prime "member here you know" but they where out until the 22nd and did not include the remote controller which is an $80 unit. Also due I live in NY Metro area I get super fast two day shipping

Installed in about 4 hours includes draining and removing the old stand up unit. If you have extra cash get a on demand install kit much like SKU 54443WPR, will save you some time on sweating all the valves need for servicing the unit down the road.

Fills my Deep soaking tub while washing dishes with no issue.

Will work great in my 2 bath, four family members house.

Thanks Supply House.

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

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

    Q:

    Can this be used with a 20lb propane tank?
    Asked on 2/24/2015 by LB from CA

    2 answers

    • A:

      Yes, I have done this on a temporary basis (that became weeks) and it worked flawlessly. No worries operationally. Only issue might be usage of propane relative to a small tank.

      A:

      with the correct regulator it should work, you should consult Takagi or an installer to verify.

    Q:

    I'm thinking of using this to replace my current 40 gallon unit. My current unit vents straight up and then joins in with the Furnace exhaust before the roof. Will I need to change this setup, or will this unit exhaust just fine with the furnace?

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

    Q:

    Hello, I am trying to use this for a hot water heating system.

    The system will operate just fine at 122F, however when trying to get the temperature to go up from 122, the control panel will not let me and beeps 3 times.

    I can adjust down just fine.

    The propane pressure is 12.5.

    Cannot think of what else to do, still waiting around to hear back from Supply house.
    Asked on 1/6/2015 by BigTires001 from Pittsburgh, PA

    • A:

      After talking with takagi they determined it had to be something with the computer control board. I had another one and it worked perfectly.

      Just a side note there are many variations of this heater, they all have the capability to reach 167F. Does not matter about flow rate, fuel type etc' The only factor you must have it the control panel to set above 140F, which comes with it and I feel is very useful for determining Delta T and flow rate.

      If you do not have the control panel for some reason there are dip switches on the low voltage panel that allow you to manually set the temp from 122F to 140F in a few increments.

    • CUSTOMER CARE

      A:

      you would need to contact Takagi, that maybe the max temp based on entering water temp & flow rate.

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

    Q:

    Will this unit work as a back up for a solar water heating system? Will the water flow through when it is hotter than set temp? Or would I need to run some sort of by pass system? The coolest the solar water ever gets is @ 90F not quit hot enough for a good shower.Thank you for the info.
    Asked on 12/2/2014 by kwikenuff from stony point,nc

    2 answers

    • A:

      Yes. The Takagi will simply stop burning fuel if the water is within about 5 degrees, soon as the temperature gets lower it will slightly top off the temp to you desired level.

      Also if you use the included control panel You can still watch the water temperature on the inlet and outlet as well as the flow rate even if the takagi is powered off by the control panel or it is simply not heating water.

    Q:

    I need to know more about the direct vent. My current tankless is vented thru the chimney and seems to be fine. Nothing else uses the flu. What problems can I have if vented that way?
    Asked on 10/26/2014 by Jill from kansas city mo

    1 answer

    • CUSTOMER CARE

      A:

      often these direct vent will not have the pressure to properly exhaust if the flue is not run as per manufacturers guidelines.

    Q:

    Does this unit need a pressure release valve on the output?
    Asked on 10/11/2014 by Richard from United States

    2 answers

    • A:

      Yes you will need a pressure relief valve. The gentleman before me suggested these isolation valves which I also suggest: http://www.supplyhouse.com/Takagi-TM-IV50-AB-Lead-Free-Isolation-Pressure-Relief-Valves-1-FNPT-x-FNPT-T-M50

      However I would only add to that by mentioning that the pressure relive valve itself is a separate piece screwed into the hot side of the isolation valve kit. The actual pressure relive valve that comes with the kit is 150PSI, which is way too high for todays radiant heating systems. If running a radiant heat system I would suggest 30PSI for the relief valve itself as you typical run these systems from 12-15 psi.

    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.
