A. O. Smith has launched its newest high-capacity, residential water heater, the Promax® 55-gallon atmospheric vent gas water heater.
The NAECA III-compliant model boasts 60,000 BTUs of power and 65-gallon per hour recovery – 50 percent higher than a standard 50-gallon gas water heater. This combination of storage capacity and high output makes it a choice well suited for higher demand combination hot water supply and space heating applications.
It was developed to fill a void between the 50- and 75-gallon products left when the 65-gallon high recovery model was discontinued due to the 2015 update to the NAECA III federal efficiency rules. Both natural gas and propane models are available.
