Product Details
✓【Up to 10.3 GPM Whole-House Hot Water】With 199,000 BTU of heating input, MIZUDO tankless water heater gas supports simultaneous hot water demand across 2–3 bathrooms, kitchen faucets, sinks, laundry and dishwashers, making it an ideal upgrade from traditional 50-gallon tanks for busy households.
✓【±1°F Precise Temperature Control, Up to 149°F High-Temp】Advanced gas modulation of water heater helps maintain water temperature within ±1°F, reducing sudden hot-and-cold fluctuations. Featured with a default 107°F daily comfort setting and an adjustable range up to 149°F, the on demand water heater is perfect for deep soaking tubs, sanitary dishwashing, and heavy-duty laundry cycles.
✓【0.53 GPM Low-Flow Activation, On-Demand Efficiency】 The gas tankless water heater responds to lower-flow hot water supply for faucets, showers, and other fixtures. It heats water only when needed, helping reduce standby heat loss compared with traditional tank water heaters.
✓【Smart WiFi Control】In addition to the LED display, you can manage your gas water heater from anywhere via App: check operating status, fine-tune temperature, and get instant abnormal alerts. Compatible with Amazon Alexa, delivering a truly connected, hands-free bathroom experience.
✓【Reliable Long-term Warranty】MIZUDO tankless water heater offers a 2-year full unit warranty and 5-year heat exchanger coverage, backed by professional 24/7 customer support. *In cold climates, open the pressure relief valve to drain residual water if the unit remains unused for extended periods. *Not recommended for use at elevations above 3,000 feet.
✓【Outdoor oxygen Combustion, No Backflow】The sealed concentric direct-vent system of this tankless gas water heater draws outdoor air for combustion and uses a dedicated 3" × 5" concentric vent kit. The bottom-mounted forced-draft fan expels exhaust gases outward, effectively preventing backdraft and keeping fumes out even in windy weather.
✓【CSA Certified for Indoor Installation】This compact tankless water heater gas indoor(24.8" x 15.9" x 10.4") is roughly the size of a carry-on suitcase, easily fitting into closets, basements, or laundry rooms to free up valuable home space. It uses a standard 120V power supply with 3/4" NPT connections. Professional installation recommended.
