  • Our take on the Takagi T-H3-DV-N

    The Takagi T-H3-DV-N is a condensing, natural-gas tankless water heater rated at 10.0 GPM and 199,000 BTU, built for large homes and light commercial use. It runs at up to 0.95 UEF and is ultra-low NOx, so it meets some of the strictest air-quality rules in the country. It vents with PVC through a two-pipe direct-vent setup, which keeps installation flexible. Reviewers and installers rate it for output and efficiency, but it needs a gas line and venting sized for its full input, and the front-panel controls are basic next to units with app control.

    Questions and answers

    Is the T-H3-DV-N big enough for a large home?
    At 10.0 GPM and 199,000 BTU it suits large homes with several bathrooms and light commercial use. Very cold incoming water lowers real-world output.
    Does it need special venting?

    Can I control it from my phone?
    No. Temperature is set on the front panel, from 82°F to 130°F, with a 140°F maximum. There is no Wi-Fi or app control.
    Is it good for areas with strict NOx rules?
    It is ultra-low NOx and CSA listed, which helps in regions with tight air-quality limits. Check local rules before buying.
    What maintenance does it need?
    Flush the heat exchanger periodically to clear scale, especially with hard water, and keep the condensate line clear. Diagnostic codes help with troubleshooting.
