Moving from a hot shower into a chiller atmosphere leads to a quantum drop in body temperature leaving a peaceful state of mind. Fully-modulating tankless gas water heaters add a spin of luxury to residential applications.
They can generate hot water to run two or more bathrooms. Unlike mainstream tank-style water heaters, powerful tankless water heaters do not cut off hot water in the middle of your soothing bath. After combing through the market doggedly, we hit upon a world-class and renowned model presented by our Takagi T-KJr2-IN-NG Indoor Tankless Water Heater Review.
The T-KJr2 delivers hot water to residential hot water systems usable with residential high flow rates and radiant heating applications.

Takagi T-KJr2-IN-NG Indoor Tankless Water Heater Review |5 Major Features
A. Fully Modulating & Durable Heat Exchanger
The Takagi T-KJr2 operates with a fully-modulating, computer-monitored burners and electronic ignition that only consumes the amount of gas according to your preferred temperature level. You can connect directly or indirectly, storage tanks, recirculation patchworks, radiant floor system, domestic and heating applications.
It significantly upgrades the unit’s efficiency while it cuts back your gas bill. Commercial-Grade copper heat exchanger guarantees corrosion-repellent properties. Copper improves thermal conductivity by 25x times than stainless steel, thus, stabilizing outlet water temperature fast.
The energy furnace’s design can sustain indoor applications with a super-hot copper heat exchanger that preheats water on demand. It checks in at an energy factor of 0.81-0.83.
B. Efficient Performance & Simple Use
Takagi T-KJr2 matches the performance of a 40-gallon tank-type standard unit. Despite having the smallest size in the all Takagi product line-up, it shines on the bleeding edge of technology and packs a punch to facilitate a regular flow of hot water for a household.
You can use its remote control to adjust adding more convenience. Gas-powered and vented to the outside, it has roughly 0.5 GPM activation rate. It works on an unobtrusive display that gives you quick access to modulate settings from 98-to140 degrees.
The unit guarantees constant water temperature with thermistors and boasts an air-fuel ratio (AFR) sensor that detects efficiency and thus diminishing toxic emissions.
C. Heat Output and Flow Rate
You can generate hot water to run up to two bathrooms in warm climates. The Takagi T-KJr2 does not guzzle electricity with the gas-fed operation. It renders input somewhere in the neighborhood of 19,500 to 140,000 BTU/hr.
It has a flow rate of 6.6 gallons per minute (GPM) at 350 F while the heat output can climb to 70 F at 3.3 GPM. The unit can support hydronic baseboard and radiant floor heating functions. You can go, Takagi, if you have a small or medium-size family with slightly low demand for hot water.
Unlike traditional storage-style tanks that clog with deposits and corrosion or pilot light that fritters away gas, it ensures you never run out of hot water.
D. Temperature Remote Controller
The Takagi T-KJr2 includes a remote control and power cable as standard accessories. The Temperature Remote Controller included (TM-RE02) lets you adjust readings beyond the factory settings and acts as a diagnostic instrument for error codes.
It shows a concise error code that pinpoints a problem with the system making it easier to troubleshoot. You can adjust incoming or outgoing water temperature within the range of 99°F to 167°F.
It makes it easy to reset the temperature level of the unit while you can install in a remote location several feet away. A manual Hi-Limit Switch, however, prevents water temperature from exceeding the safe limits.
E. Device-Defensive Technology
The Takagi T-KJr2 protective system shields against the internal freeze, overheating, and surge. The troubleshooting diagnostic error codes resolve mechanical failure quickly. Built-in scale and leak detectors prolong unit’s lifespan and forestall water damage respectively.
Takagi’s proprietary Air-Fuel Ratio (AFR) sensor regulates and maintains efficient combustion throughout, tweaks fan motor speed for proper air/fuel proportion, and diminish emissions and maximize performance. The unit also comes with Exhaust and Water Temperature Safety Control for advanced protection.
Its Overheat Cutoff Fuse inhibits breaches in the heat exchanger reservoir. Loads of safety packages will keep it functional for years.
Why should you use Takagi T-KJr2-IN-NG Indoor Tankless Water Heater?
Compact and Snugly-Installable
The Takagi T-KJr2 has compressed dimensions of merely 20.5" x 13.8" x 6.7" allowing you to install the potent tankless water heater anywhere. The subtle shape allows indoor installation proximately than conventional tank-type heaters, which cuts back flow-time through ducts and dissipates less energy.
Flow Rate Proper for Residential Applications
The unit heats water flows at 6.6 gallons per minute (GPM) maximum. The flow rate renders ample thrust for light residential uses with one to two bathrooms in a small home, condo, cabin, or apartment.
Commercial-Grade Copper Heat Exchanger
Premium-quality copper alloy with superior heat-resistance, higher tensile strength and maintains hardiness and a fine grain at extreme temperatures. Commercial-grade copper alloy offers resistance to the damaging impacts of erosion that causes leakage in heat exchangers.
Endless Hot Water
Since it heats water as you use it, you will never fall short of hot water ever. It takes nanoseconds for the water to hit your preferred temperature. The Takagi T-KJr2 will continually drive a stable stream of warm water to meet the demands of your applications.
Energy-Efficiency & Plethora Savings
Unlike conventional tank-type water heater that warms up and holds a set volume of hot water, the unit only activates as you use h2O. It does not lose standby energy for more efficient heating and energy conservation.
