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.
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.
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.
