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.

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.

SYSTEM PROTECTION

Isolation valves provide an extra measure of protection, making it easier for pros to service your tankless system.

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.
