The ultra-low-NOx natural gas water heater line includes 18 models with stainless steel radiant burners that reduce nitrogen-oxide emissions by 75 percent from previous low-NOx models, the company says. Tanks range from 28 to 50 gallons, including tall and short models, with gas inputs of 30,000 to 40,000 BTU/hour. The line includes a self-cleaning system and a flammable vapor ignition resistance system that quickly shuts down the water heater should vapors ignite within the combustion chamber. 770-351-3000. www.rheem.com.
