Rinnai Tankless Water Heaters Earn Energy Star

Rinnai Corp., a gas appliance and tankless water heater manufacturer, recently announced that six models from its line of tankless water heaters have earned the U.S. Department of Energy's and Environmental Protection Agency's Energy Star® rating for energy efficiency, including its flagship models, the R94LS and R75LS.

"Water heating presently accounts for 15.5 percent of national residential energy consumption, making it the second-largest energy user in homes," said Phil Weeks, general manager of Rinnai America Corp. "With rising energy costs and a continued commitment to environmental stewardship, consumers are focused more than ever before on maximizing their homes' energy efficiency. By developing Energy Star-qualified tankless water heaters, Rinnai is helping consumers save money while simultaneously decreasing their carbon footprint."

To qualify for the designation, tankless water heaters must maintain a minimum Energy Factor (EF) of 0.82 and a minimum gallons-per-minute flow of 2.5 at a 77-degree Fahrenheit rise. A whole-home gas tankless water heater that meets these requirements is expected to reduce energy use by 30 percent, which can save a consumer approximately $108 in annual energy costs when compared to a typical gas storage water heater.
