【Instant On-Demand Water Heater】 Natural gas-driven, on-demand water heaters are more energy-efficient than traditional tank water heaters, offering steady, reliable performance and safety features such as a flame failure device, anti-freezing protection, and overheat protection. They require just 3.6PSI of water pressure to deliver 7.4 gallons of hot water per minute, with a maximum temperature increase of 167°F.

【Super High Efficiency】 This tankless water heater is energy-efficient and provides hot water on demand, eliminating standby energy losses associated with storage water heaters. With a 7.4 GPM output and a maximum power output of 170,000 BTU/hour, it ensures on-demand hot water for up to 3-4 simultaneous bathroom fixtures. Compact and highly efficient, it provides ample hot water for both bathrooms and kitchens.

【Durable and Safe Construction】 Crafted from high-quality stainless steel, this gas tankless water heater offers exceptional temperature resistance and corrosion protection. Featuring a built-in oxygen-free copper water tank and a powerful DC motor for whisper-quiet operation, it ensures stable combustion without noise. Equipped with advanced safety features such as a leakage protection switch and a smart digital display, you can easily adjust the temperature between 86°F and 167°F.

【Easy to Install and Use】 This water heater is compatible with standard 1/2" NPT water fittings and gas inlets, and comes with a 2.5" horizontal vent pipe for quick installation. It improves air quality by reducing greenhouse gas emissions. For optimal performance, proper ventilation and a smoke exhaust pipe are required.

【Versatile and Space-Saving】 Compact and easy to install, this product saves over 50% of the space required for tank water heaters. Ideal for homes, small cabins, and remote apartments, it also eliminates the need for an expansion tank. In cold weather, if the heater is unused for an extended period, opening the pressure relief valve can drain residual water to ensure safety.
