  • Space and Resource Saving:

    This size of this device is 6.7×13.8×20.3 inches and weighs 37 pounds. For those able to install a tank water heater, the colossal amounts of space that is eaten are huge. This is disadvantageous especially to those that stay in a rented unit which has limited space. However, with the Takagi T-KJr2-IN-NG Indoor Tankless Water Heater, space is not a matter of concern. With the dimensions mentioned above, this device is pretty small and readily portable for anybody. This heater has a gas input of 140,000 BTU rendering its energy saving and being the most appropriate for those whose residential usages are fixed at that specific level.

  • Great Capacity:

    This device has a maximum flow rate of 6.6 GPM at a temperature of 35°F. At 70°F, the maximum flow rate of the water heater clocks at 3.3GPM. This helps it in minimizing the chances of scalding.

  • Safety:

    Takagi, the Japanese manufacturer is keen on specific details on the safety of the product. In this, the creativity of the manufacturer is seen at play as the venting system rocks a category III stainless steel. This is quite unique and ideal as other players in this sector opt for plastic or even copper vents.
    Still, on the safety feature, the tank-less water heater is fitted with the ‘overheat’, ‘freeze’, and ‘surge’ protection capabilities. In addition, there are codes for troubleshooting in case of an operational safety issue.

  • Warranty:

    The company, Takagaki, has been able to include a 10-year heat exchange warranty. This shows that the manufacturer is keen on the quality of the product and wants it to serve you wholly for the longest time possible. For parts of the heater, a warranty of 5 years is applicable. However, it is for residential abodes only and 5/3 in commercial applications.

As much as this heating device has awesome features and numerous benefits, it does not lack one or two cons. However, these disadvantages are not very dire and can be circumnavigated effectively. Some of these will include:

  • Lag Time in the Supply of the Hit Water:

    In order to have a smooth flow of hot water, you will have to wait for approximately 7 seconds. It leads to a scenario whereby there is a chance of freezing especially if the temperature of the inlet water is too low. However, this problem is not largely due to the tankless heater. After all, this is a common issue with a tankless water heater. The phenomenon occurs as there are small amounts of water in the pipes and consequently must get out the next time the device is in use. You can avoid this issue by turning on the shower for at least 10 seconds then waiting for the normal process to follow suit.

  • Expensive after Sales Costs:

    The manufacturer states that for the warranty to be valid, the device must be installed by a licensed technician. This can be a bit expensive for some individuals especially the low-income earners.
    However, it is possible to carry out self-installation since the device comes with a clear and descriptive manual which is quite easy to understand. On this note, if you are not willing to take the time to read the manual, it is advisable that you bear the costs of a licensed installation as improper installations of natural gas devices could lead to fatalities.
