The T-K3 is Takagi's most versatile and powerful unit that allows you to connect up to four units without the use of an additional controller unit. The T-K3 can also be converted to a direct vent model.

There are many features that make this unit stand out from the rest:

  • Compact Size: Only 13.8 inches wide, the T-K3 can be recessed between wall studs for even more space savings! A special recess box is available for outdoor installations.
  • Lower Activating Flow Rate: The T-K3 activates at only 0.5 GPM, which allows the use of smaller water flows in bathroom sinks and showers. This reduces water waste and allows for stable temperatures.
  • Parallel Installation: Using Takagi's Easy Link technology, the T-K3 can be installed in parallel with up to three other units without the use of an additional control box, generating more flow while saving money, space and installation time. Four T-K3 unites will deliver a total of 21.6 GPM at 60 degrees F delta T; or 26 GPM at a 50 degree F delta T.
  • Direct-Vent Conversion: The T-K3 can be easily converted into a direct vent model for inside installations that need to import combustion air from outside.
  • Eight Temperature Settings: Instead of the usual four settings, the T-K3 offers eight separate temperatures, set by dip-switch: 104 degree F, 113 degree F, 122 degree F, 131 degree F, 140 degree F, 158 degree F, 176 degree F, and 185 degree F. This versatility reduces the need for a separate remote control. However, setting temperatures other than the eight presets requires the TM-RE10 temperature controller.
  • Longer vent runs: The T-K3 can have a vent pipe run up to 50 feet with five elbows, instead of the normal 35 with three elbows.

      As you can see, the T-K3 incorporates all those "why-don't-you-have-this?" features into this one new product. Its larger flow capacity through parallel connections will meet the hot-water needs of most high-volume residential applications and many commercial projects, too. In short, the T-K3 fills the gap between the single residential heater and multiple commercial T-M1 units. Performance depends on the temperature of the ground water of course: At a delta T of 60 degrees F in warmer areas - for example, where the winter ground water is 60 degrees F and with the output set at 122 degrees F - the T-K3 will provide a 5.4 GPM, or 324 GPH. In colder areas where the input temperature may be 40 degrees F or less, expect a flow rate about 4.1 GPM, or 246 GPH.

    • Technology to meet today’s demands

      From bathroom to kitchens, the latest trends in home design all add up to one thing: a growing demand for hot water throughout the home. With an average soaker tub holding 70 gallons of water, today’s homes need more than an old-fashioned 50-gallon tank of hot water to keep up. They need the consistent, never-ending supply of hot water you can get with a tank-less hot water heater from Takagi.

    • Up to 50% energy savings

      Not only does Takagi provide you with plentiful and endless hot water…it does it in the most energy-efficient way possible. Instead of keeping a whole tank full of hot water while you’re not using it, Takagi instantly heats only the water you need.

      A Takagi tank-less heater can pay for itself in energy savings alone. As of January 1st, 2006, homeowners are eligible for a $300 federal income tax credit by installing energy-efficient water-heating units from Takagi

    • A legacy of innovation and dependability

      For more than sixty years, Takagi technology has been efficiently heating water in homes around the world. We’re so confident of the quality, dependability and long-term performance of our products that each model carries a ten-year warranty on the heat exchanger and a five-year warranty on all major parts.

    "This product is great. It cost me a lot to have it installed and I kept the original hot water heater tank as a back-up with a shut off valve since the tankless doesn't work during a power failure. Overall, I love the endless supply of hot water. The only other downside besides installation cost …"  Read Full Review »

    "Hi, We recently purchased a Takagi T-K3 Flash Hot Water Heater (Tank-less)/(Natural Gas). [...] The Takagi T-K3 Flash Tankless heater performs just as advertised. It is a good feeling to know we don't have a tank full of water being heated during a time we don't use hot water to just sit and be heat …"  Read Full Review »

    "My Takagi tankless required a $120 repair after 5 years and the heat exchanger failed after 6 years requiring replacement. Warranty is only good for 5 years - don't believe the expected life of these things; if the expected life was really 15 years the warranty would cover a longer period. "
