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.

FLEXIBLE OPTIONS

Rinnai tankless water heaters are available using either natural gas or propane and for installation indoors or outside. You get the flexibility to choose the unit that works best for your home.

EFFICIENCY YOU CAN TRUST

Formerly Energy Factor ratings, the new industry standard of Uniform Energy Factor (UEF) measures energy efficiency in water heaters. The higher the number (up to 1.0), the better the performance efficiency.

SEAMLESS SERVICE

Our Rinnai Control-R™ wireless module and mobile app take convenience and flexibility to the next level. With it, Rinnai independent dealers seamlessly assist customers via remote diagnostics, ensuring maximum comfort and convenience.
