Takagi T-KJr2-IN-NG Indoor Tankless Water Heater, Natural Gas

Released in 2010, the T-KJr2-IN & T-KJr2-OS are the smallest water heaters in the Takagi tankless line. This small, but the power 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.

☆ But overall super pleased. 3 full bathrooms

Everything I expected. Water heater busted, bought this and had it installed. Please note that you need to buy additional materials such as stainless steel exhaust vents, hoses, fittings and whatever else to make sure the installation is up to codes and follows the instructions. The additional material cost me under 400$. Could possible be cheaper if you’re a savvy shopper but I didn’t have the time. 4 stars only because there were so many additional things that needed to be purchased. But overall super pleased. 3 full bathrooms, 2 adults, 3 kids and no issues yet. Otherwise, I can marry it up to another system.

 I highly recommend this unit

This little unit is everything it said it was. An endless supply of hot water. Even when you turn on other faucets in your home it just keeps producing hot water. I highly recommend this unit.

 Works perfectly.

Wonderful product, I used pex and bought the filter and valves to hook it up. I did it all myself and Lowe’s has all my double wall exhaust pipe. I also had to run some gas lines 3/4 inch hooked directly to the unit. After all that, it works perfectly and the water is super hot and 100x better than my old electric unit. Love it!

So far love this water heater, but had a very bad experience with the installer through Amazon. The person arrived on time as scheduled but was not a qualified professional. Called his supervisor before starting job who said since my current heater wasn't tankless that I should by for a new installation instead of replacement. Told him I wanted to cancel, then he offered a 'deal' if I dealt directly with him and not through Amazon having no hot water for a week, I took the offer. Installer left exposed wiring out of the electric outlet he tapped into, definitely not up to code. Used duct tape to 'seal' gas exhaust pipe to outdoors. Gave me his personal card at end of job for his own side business as a professional painter. Next time I will hire my own professional!

We did a great amount of research before buying this product! Even called Rheem to make sure the guarantee was in place if purchased through Amazon. It is! We had debated about purchasing a Tankless Water Heater when we purchased the previous one in 2006. In 5 1/2 yrs it was completely rusted through at the bottom and was leaking! This time we decided to go Tankless and are so glad we followed through! We bought the condensing one and feel that is imperative! It worked perfectly from the beginning. We are only two but purchased this with an eye to the future of a larger family living here!

    Incredible, what else is there to say? We bought this water heater for our RV, and it has been a dream! We fulltime in our RV, and use it on a daily basis. The only time we have issues is when the water pressure is too low, not a fault of the heater. We read reviews that complained about the freezing issue, we mounted the unit on an inside wall perpendicular to the outside wall to where it was vented. This kept the coils away from the colder outside wall, and yes it got cold this winter, and we never had one issue with freezing.

    By Paul

    I love Japanese baths. My outdoor tub had a wood fired heater for years and it finally sprung leaks.
    So far; heats 400 gallons to 112 f in about 3 hours ? (not measured) Faster than the wood stove and a lot less work.Circulation with a large aquarium pump works well I think if the heater is in a cabinet it will think it's indoors. GOOD!

    By Kethie

    If you have LP and want a water heater that never runs out, this is amazing! Easy to install (if you are a plumber/HVAC competent individual) and very lightweight. The customer service from the company in response to our inquiries before purchasing this was quite knowledgeable as well.
    Keep in mind that you cannot run every single hot water appliance at the same time (dishes and bathing doesn't work as well). It is much more efficient than the tank water heaters.
