American Standard Water Heaters Energy Star-certified products
September 18, 2014
American Standard Water Heaters announces its high-efficiency series commercial and residential water heaters are officially Energy Star-certified. The Energy Star program is a voluntary labeling program jointly administered by the EPA and DOE. The new design dramatically reduces clearance space as the HE series can be installed directly onto the floor. Customers have the option to upgrade their warranty to five years.
