This series offers nine models for high-efficiency domestic hot water in residential or commercial applications, adding new features for easy installation, operation and maintenance. Recently recognized as a CES 2017 Innovation Awards Honoree, the series features an Energy Factor of 0.99 with Thermal Efficiency of 100 percent. This series achieves temperature stability of plus- or minus- two degrees Fahrenheit through the active bypass. Its technology controls output capacity, optimizing comfort and efficiency by combining the burner's pulsating mode with the bypass valve to achieve the desired outlet temperature. Its wide operating range – between 9,000 and 199,000 Btu, saves energy when hot water demand is low.
The 9900i SE model has a glass front and integrated Wi-Fi control – also an option on other models – enabling the homeowner to control water heater remotely via a free mobile app. Outdoor models feature a concealed, built-in controller with optional Wi-Fi connectivity.
Each model offers conversion to LPG using the included manifold injector kit, which eliminates stocking both LP and NG units, thus saving the wholesaler’s inventory cost.
These models offer primary and secondary heat exchangers for longer lifespan, and deliver water supply temperature to 180 F. Systems also can be cascaded up to 24 units to achieve flow rates of more than 200 gallons per minute – ideal for commercial buildings, schools and hotels.
