A. O. Smith adds 55-gallon atmospheric vent gas model


Promax Gas Vent ModelAshland City, Tenn. – Leading water heater manufacturer 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 unique 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 powered models are available. 

“The new A. O. Smith 55-gallon Promax® Atmospheric Vent is a high performing water heater on a number of fronts - storage capacity, input, output and recovery for atmospheric models,” said David Chisolm, vice president of marketing for A. O. Smith. “This model is well suited for larger families with a high demand for hot water, especially where replacement options may be limited due to installation requirements.” 

A. O. Smith’s 55-gallon Atmospheric Vent is available in 6-year and 10-year limited warranty models.
