Rinnai

Hard Working & Honest, Our Name is Our Promise!

Rinnai.

More homeowners and business owners choose Rinnai than any other tankless water heater brand. They choose us for our 100-year commitment to quality, for our industry-leading warranties, and because we're the first major tankless brand to manufacture in the U.S.A.

RU Models

Enjoy all the comfort and performance you expect from Rinnai, for less, with our super high-efficiency plus RU models. These compact units are powerful enough to meet your needs, consistently delivering hot water in up to four places around your home at the same time.

Better Value Than a Tank

Rinnai tankless water heaters last up to twice as long as tanks and have twice the warranty length. Plus, they save energy by heating water only when it is needed. Consumer financing and rebates are also often available.

Technology to Improve Your Lifestyle

Rinnai Circ-Logic™ technology allows you to use an external pump to setup recirculation patterns that coincide with your habits. You can ensure hot water is available when you need it, without the expense and inefficiency of circulating it during times of inactivity.

Reliability You Can Count On

Every Rinnai tankless water heater is individually tested for quality before shipping. Unlike many competitors, Rinnai makes the majority of our key components, allowing for consistent control of quality. That's why more consumers and businesses choose Rinnai over any other tankless brand.

Flexible Options

Enjoy the flexibility to choose the unit that works best for your home. Rinnai tankless water heaters are available with natural gas or propane fuel options and can be installed inside or outside.
