Features:

• [Save 17% & Go Greener] – With 0.91 UEF high-efficiency. This ThermoMate condensing tankless water heater cuts annual hot water costs by about 17% compared to traditional models. Its dual heat exchange system, featuring a stainless steel condensing heat exchanger and an oxygen-free copper heat exchanger, captures and reuses waste heat that traditional models lose, minimizing energy bills and reducing carbon emissions. Enjoy reliable comfort while making an eco-friendly choice.
• [Whole House Use] - This instant water heater can supply three showers simultaneously, each delivering 105°F hot water at a flow rate of 2 GPM, based on an inlet water temperature of 62°F. In warmer climates with an inlet water temperature above 77°F, it can deliver up to 9.38 GPM of on-demand hot water. With no waiting time and no cold-water shocks, it’s perfect for busy households, capable of running showers, laundry, and kitchen tasks at the same time with ease.
• [CSA Safety Certification] - Equipped with 8 protections: boil-dry, freeze, flame-out, overheating, over-temperature, pipe blockage, high-temperature lock, and excessive air pressure. This CSA-certified natural gas tankless water heater is fitted with 4 ceramic heating cores and automatically activates frost protection when the temperature drops to 41°F. The energy-efficient system uses minimal electricity to provide gentle warmth, preventing pipe ice buildup without high energy costs.
• [Constant Temperature & Quiet] - Featuring intelligent water mixing valve technology that automatically and precisely regulates flow to ensure stable output temperature—achieving zero fluctuation and instant adjustment, even during simultaneous multi-shower use. Combined with a sealed combustion design that enhances efficiency while significantly reducing operational noise for a quieter, more comfortable home.
• [Discharge and Treatment of Condensate Water] - As a condensing unit, this indoor tankless water heater produces mildly acidic condensate water that you will need to discharge into a drain. We recommend installing an economical external condensate neutralizer kit (not included) at the drainage point. This simple add-on neutralizes the acid, protecting your pipes from potential corrosion.
