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 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.

☆ 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 what ever 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 much additional things that needed to be purchased. But overall super pleased. 3 full bathrooms, 2 adults, 3 kids and no issues yet. Other wise, I can marry it up to another system.

 I highly recommend this unit

This little unit is everything it said it was. 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. 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!
