Go Green While Saving Green

Rinnai has earned ENERGY STARĀ® approval by consuming less energy and reducing greenhouse gas emissions, energy efficient guidelines set by the U.S. Environmental Protection Agency and the Department of Energy.

Traditional tank water heaters can take up to 16 square feet of valuable floor space. By contrast, Rinnai Tankless Water Heaters are about the size of a carry-on suitcase and can be installed on virtually any wall inside or outside of your home.

Rinnai Tankless Water Heaters last up to 20 years. That's two to three times longer than conventional tanks! Investing in Rinnai means reducing landfill waste while experiencing countless hours of satisfaction with one of life's most essential needs: hot water.
