Takagi T-H3-DV-N Condensing | Review

Takagi T-H3-DV-N

A good hot water heater can provide you with so much supply that you never need to wait around before taking a shower or bath, even if someone else in your family just showered. The Takagi T-H3-DV-N Condensing High-Efficiency ( Check price on Amazon )  is a solid tankless hot water heater that provides you with a good amount of supply in a limited amount of time.

This brand has a 10 gallon per minute flow rating and works in most climates. It doesn’t take up much space and comes with instructions for installing the device yourself.

Final Verdict

Takagi T-H3-DV

We wouldn’t recommend the Takagi T-H3-DV-N for homes in cooler regions because it may not hit the temperature or flow rating that you want.

It does work great for those in warmer climates and gets our nod for those who need a water heater in the spring or summer.
