ENERGY STAR ® CERTIFIED
ENERGY STAR-rated water heaters meet strict efficiency standards. While all Rinnai water heaters use less energy than tank water heaters, our condensing units use even less, saving you more.
CONTROL AT YOUR FINGERTIPS
Our enhanced Control-R™ 2.0 mobile app features timers and schedules throughout the day and even allows you to remotely put the system into vacation mode when you’re away.
FASTER HOT WATER DELIVERY
Rinnai Circ-Logic™ technology allows you to set recirculation patterns that coincide with your typical habits. Hot water is available when you need it, without the expense and inefficiency of circulating it during times of inactivity.
Isolation valves provide an extra measure of protection, making it easier for pros to service your tankless system.

Rinnai is an industry leader, proven when we became the first water heater with Amazon Alexa integration. Use more than 20 voice commands for on-demand voice activation of the system.
