Takagi T-D2-IN-NG Review

Takagi T-D2-IN-NG Pros and Cons

The Pros

The Takagi T-D2-IN-NG is an Indoor Natural Gas tankless water heater that is capable of producing up to 10.0 Gallons per Minute. This particular unit from Takagi is Energy Star Certified and is specifically designed for light commercial use applications.

The Cons

While the Takagi T-D2-IN-NG can provide enough continuous hot water flow for the majority of homes, it may be too large for smaller homes. Technically this tankless water heater is intended for light commercial use so it is more heavy duty than other tankless water heaters for normal residential use.


There are some great qualities to the Takagi T-D2-IN-NG and it comes highly recommended from people who have purchased it. It produces a ton of hot water and is still very energy efficient. For those reasons I would definitely recommend it to those needing this type of water output.

Where to buy the Takagi T-D2-IN-NG

You can purchase the Takagi T-D2-IN-NG at different stores online or retailers. I have found that Amazon typically has the lowest prices on not only this tankless water heater but most tankless water heaters. Amazon might also have an option to buy used first so definitely check with them first.
