The 310 Series is the most versatile and popular tankless model we offer. The 310 features a max flow rate of 8.0 gallons per minute providing enough hot water to run three showers at the same time. Remote control included as a standard feature. Provides a variety of installation options: indoor, outdoor, and direct vent.
The ATI-310-N tankless water heater uses up to 190,000 BTUs of natural gas to deliver a max flow rate of 8 GPM. It utilizes non-condensing technology to achieve an Energy Factor of 0.82. This model meets Low NOx emission requirements, and comes with a 15-year limited warranty.
The comprehensive line of A. O. Smith tankless water heaters provide hot water on-demand. When a hot water tap is opened, a flow sensor sends an activation signal to the onboard computer. The computer then activates the combustion system. Heat is transferred to the water as it flows through the heat exchanger and an outgoing water temperature sensor keeps water temperature to within +/- 1F of set point. Once the hot water tap is closed, the heater automatically turns off.
