Rinnai Corp. received the Super Nova Star Award by the Alliance to Save Energy. The award is given to organizations with less than $150 million in annual revenue that have shown leadership in energy efficiency.

“With today’s rising energy costs, it has become increasingly important to provide innovative, cost-effective and energy-efficient solutions to our consumers, while at the same time maintaining a commitment to environmental conservation,” saidPhil Weeks, general manager of Rinnai America Corporation.

“We are honored to be recognized by the Alliance to Save Energy and will continue to make strides which underscore our long history of innovation in the energy efficiency of tankless water heaters.”

Rinnai tankless water heaters are up to 30 percent more energy efficient than a traditional natural gas water heater and up to 50 percent more efficient than an electric tank water heater. Because they spend energy to heat water only when needed and shut off automatically when the water supply is closed, Rinnai tankless water heaters provide users with significant energy savings.
