When it comes to the question of a house with many people, deciding which tankless water heater to buy becomes critical. Many tankless water heaters support three faucets at a time, but you sometimes cannot use more than two faucets simultaneously if you live in a cold climate like 35-degree temperature. Takagi T-H3-DV-N Natural Gas Indoor Tankless Water Heater addresses the ‘significant need’ problem. With gas inputs of 199,000 BTU, the T-H3 natural gas indoor tankless water heater can support four bathrooms in warmer weather and three bathrooms in colder weather. This gas water heater has the highest flow rate of 10 GPM (gallon per minute); believe me, I have written many reviews, but this much GPM is rare.

Features of Takagi T-H3-DV-N
Capable of producing a considerable volume of boiling water
With 10GPM flow and intake of 19k BTU of natural gas, you may have already guessed that this is a jumbo offer for the water heater. Though Takagi conservatively says it covers four bathrooms, it can easily cope with 5, 6 bathrooms, dishwasher, and washing machine simultaneously. The extra GMP only increases its capacity and ensures in a big family, no one runs out of hot water in the middle of the shower.
This unit comes with a long-time warranty and conditional warranty on labor. For single-family domestic hot water needs, it gives a 15-year limited warranty; for commercial purposes, a limited warranty is for ten years, five years little parts for Residential and commercial use. There is a 6-year limited warranty on the heat exchanger. Most users say it is a complaining-free unit. SO once you have it, you can enjoy it for 15-20 years, and ROI will come up in 5 years by the electricity consumption bill.
Good for heavier purposes
The manufacture has made it hard enough, so if you own a beauty parlor, have a bar, a small café, and want a tankless gas water heater, this is the one. T-H3 is also suitable for heavier residential usages; for example, if you need it for space heating or domestic recirculation systems, it is good enough for these purposes.
Compared to tank water heaters, it is very much space-saving compact, and easy to fit in any nook of your house. With a dimension of 11.2 x 17.8 x 24.9 inches, it is as big as a laptop.
This one is loaded on the cost-cutting side with the heating system, self-modulating heating mechanism, and high energy conversion features. You can quickly get your money back from the electric consumption reduction for the first few years.

Cons with solution
It does not work on low sized pipe setting
Takagi T-H3-DV-N Natural Gas Indoor Tankless Water Heater needs 199,000 BTU gas inputs, so traditional pipeline will not work, and you will require visits to home depot for new pipes.
This is not a malfunction of the heater or your home’s pipe settings. The fact is most tank heaters use 1/2″ gas piping, so if you have used a tank heater with gas input, your pipe size is probably ½.” A heater with 200k BTU cannot run on 1/2″ very far. So you need to up-size it to higher Users recommend a 3/4″ upsizing will serve the purpose. Plus, once you up-sized in the future, you can use another heater in the same setting with the same or lower gas input need.
It is a gas-fired heater, and natural gas heaters require venting; installing it inside the home without proper venting air will suffocate.
It does need venting; all-natural gas water heaters do so. If you use PVC pipe (as small as 3 feet long), venting will become effortless, odorless, and less heat. You will not feel a thing even at the end face of the venting pipe. No chance of air or noise pollution exists. A Schedule 40 PVC, CPVC, PP, Category III stainless steel pipe is provided for venting purposes.
Await for hot water
Takagi T-H3-DV-N Natural Gas Indoor Tankless Water Heater does not give you hot water right after starting the shower.
With tankless self-sensor heaters, water gets hot only after it senses a minimum flow. This feature is designed to reduce your electricity consumption. However, it causes a delay in initial hot water flow. One solution water circulation pump with this model and attaching it with Takagi T-H3-DV-N will end up waiting for instant hot water.
The water heater is recommended to be installed only by a licensed plumber; otherwise, Takagi will not support it in future problems.
The warranty card asks you to install the unit with a licensed plumber, gas installer, or contractor. If you cannot find such an installer, do not want to spend money on installation, and are confident enough about your prior DYI skills, the good news is it is a unit with an easy installation process. If not, then it may become void for availing warranty.
