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.

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.

SAVE SPACE

Performance comes in a compact package with Rinnai tankless water heaters. They’re only about the size of a rolling suitcase, which offers flexibility to install where it’s convenient.

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.
