VERDICT

Takagi's T-K4-IN indoor tankless water heater packs in the features and advanced functions in a slim, sleek design you'll love!

Takagi’s T-K4-IN indoor tankless water heater is a liquid propane powered hot water generator with a total output of 11,000 -190,000 BTU per hour. It features a maximum flow rate of 8.0 GPM and energy factor of 0.82. This unit boasts of a simple design that will complement any bathroom. The water heater has a built-in venting system for easy installation. Although this product is designed for indoor use, you can also install this outdoors and enjoy hot water whenever! The T-K4-IN comes complete with its own DV kit for indoor installation.

Because of its added shower, the T-K4-IN is ideal for use in mid-sized residential homes with 2 to 3 bathrooms. As for the downside, some users say the unit isn’t as hardwearing as expected after several years of use. Since we didn’t test this product long enough to check for similar issues, we did not come across the same problem.

Some users also say that their T-K4-IN became prone to leaking after several years of use, something worth noting when considering this product. As for our gripe, the T-K4-IN is not the most affordable water heater there is. At almost $850, we feel that the T-K4-IN is not offering truly groundbreaking features but it does work beautifully in homes with multiple bathrooms.
