Tankless Water Heaters

Tankless Water Heaters

Upgrade Your Home; Upgrade Your Life

Rinnai tankless hot water heaters are built to commercial-grade standards and each individual unit is tested for quality. So you may never need our industry-leading warranty and legendary support for the most important appliance in your home.

Technology to Improve Your Lifestyle

Select models have the Rinnai Smart-Circ™ Intelligent Recirculation™ that learns your hot water usage pattern and schedules your recirculation accordingly, providing you with hot water faster and when you need it. With the additional purchase of a control-r™ module (compatible with most condensing models), you can integrate it into your smart home technology for greater control and have on-demand hot water in seconds.

Reliability You Can Count On

Every Rinnai tankless water heater is individually tested for quality before shipping. Unlike many competitors, Rinnai makes the vast 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.
