    A.O. Smith continues to lead the way in residential and commercial water heating with close to 70 years of innovative hot water solutions. The ATI-310C-N features the latest in efficient water heating technology along with a concentric vent design to fit almost any hot water need. Switching on when a hot water tap is opened, a built in temperature sensor helps to maintain hot water within a one degree set point during use, and the system automatically shuts off when the tap is closed saving you energy. The ATI line utilizes efficient water heating technology, providing higher than average Uniform Energy Factors and meeting Low NOx emissions requirements.
  • Concentric Vent System
  • The ATI-310C-N model features a concentric direct vent system. By combining the intake and exhaust vents into a single vent, this system helps reduce space and simplify installation by only requiring one wall penetration for venting.
  • Heavy Duty Heat Exchanger
  • The primary heat exchanger is built out of copper, offering better heat transfer than stainless steel and designed to be more resilient against corrosion. A.O. Smith water heaters are built to last and save you money in the process.
  • Multiple Safety Features
  • ATI models come with a long list of safety features standard. These include: built in freeze protection, manual reset hi limit, an overheat cutoff fuse, inlet and outlet thermistors to monitor temperatures, and a built-in flame sensor.
  • Ultra Low-NOx Emissions
  • The ATI-310C-N is designed to qualify for the most stringent Low-NOx standards. These standards coincide with SCAQMD rules and other air quality management districts.
  • Space Saving Design
  • A.O. Smith tankless heaters take up less space than their conventional counterparts. The convenient wall mount design means they can fit in nearly any home layout and offer additional flexibility.
  • Ultra Low-NOx Emissions

Ultra Low NOx Emissions NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
