T-D2-IN Takagi Tankless Indoor Water Heater (Natural Gas)

Another Takagi. The first Takagi lasted over 16 years. (Time flies when you're enjoying hot showers!) So, back for more of the same. The current model is a bit smaller physically, has gas & plumbing connections in a different location, is advertised to heat a little more hot water, and surprisingly cost about the same as the one purchased over 16 years ago. Working flawlessly. The old heater required a trip to the basement to reset it after a power outage; the new one resets itself and retains the temperature setting! Arrived well-packed. Prompt shipping. Thanks guys!

I had an older Takagi TM-1 that died after 15 years. I was looking for a replacement and was steered toward another Takagi model that is used in my area that is a lot more expensive and required more exhaust modifications. The T-D2-IN required very little plumbing modifications and is working perfectly for just about the same price as a good tank water heater. This was a no brainer for me.

USE IT AT A LAKE HOUSE THAT WE HAVE

Had the same exact unit for approximately 15 years, lived its life to the fullest. Great product so much that I bought the same one again. pretty efficient, I have 4 bathrooms, family of 7 and never ran out of hot water

This is a non condensing water heater. If you are going though a combustible wall you will need to install the sill plate. The exhaust pipe for this unit will be 350-400 degrees during operation. If I knew that I would of got a condensing water heater instead. But this water heater is a beast!!

We previously had a tank waterheater and with three daughters I was always getting in at the end of the night with no more hot water. I love that this provides an unending supply of hot water! You can hear it kick on right away when you turn on the hot faucet. I love that it has a digital interface for changing the water temp. It allows us to keep it away from scalding temps easily since we have little ones. Provides enough hot water for dish washer, washing machine, and two showers going at once. Very happy with my purchase!

Replaced my old tankless, this works fine and has added thermostat settings which are easy to use. No problem with installation and unit worked immediately. Best part of deal was the rapid response from SupplyHouse.

We use this product to heat our domestic hot water and our home through an air to water heat exchanger. There was never a problem supplying enough hot water to do both tasks. Unit worked flawlessly for 10+ years until it began to leak this spring.

My house had 2- 40gal traditional hot water heaters and I was really nervous that going tankless would have limitations for hot water on demand. My house has 5 bathrooms and we are a family of 4. Once it was installed I was able to turn on multiple showers simultaneously and had zero issues with it keeping up with demand. The only issue I had was when I installed it I used a flex gas line to make the final connection. That was restricting the flow and the unit keeps turning off as a result. I switched that to hard pipe and the problem went away. Also, the gas line near where I installed it is only 1/2" and the manual recommends 3/4". This combined with the flex gas line could have been my issue but once I used hard pipe everything worked great. It does take about 10-15 seconds longer to produce hot water at the fixture. It is very quiet as well.

Good product and the great service with very competitive prices. Ordered in the afternoon and was at my door the next day.
