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. 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.
