Rinnai tankless water heaters deliver an endless supply of hot water whenever you need it. Shower, wash dishes, and do laundry at the same time without running out. Rinnai tankless water heaters save money on your energy bill by heating water only when needed, unlike a traditional tank-style water heater that heats and reheats water all day long. Rinnai tankless water heaters are a fraction of the size of tank-style water heaters. They are easily mounted on virtually any wall, inside or out, providing more space. With a typical life expectancy of up to 20 years, Rinnai tankless water heaters last longer than tank-style heaters. Plus, they’re covered by a 12-year limited heat-exchanger warranty. With efficient technology, Rinnai tankless water heaters produce less CO2 than tank-style water heaters. ENERGY STAR qualified and up to 96% efficient, they deliver reliability.
Tankless technology that saves you time.
Never think about your hot water needs again: Innovative technology provides an endless supply of hot water whenever and wherever it’s needed – even for simultaneous uses at multiple fixtures. Showers and baths? Absolutely. Laundry and dishes? No problem. Prioritizing activities and scheduling hot water use is a thing of the past.
Save money, splurge on performance.
Designed for efficiency: Rinnai’s condensing technology features dual heat exchangers to provide maximum efficiency, and easily meet ENERGY STAR® qualifications and uses up to 40 percent less energy* than a traditional tank.
Save energy: By operating only when hot water is needed, and no storage tank to heat and reheat water, our tankless technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly uses energy.

Multiple sizes: Rinnai gives you options to right-size your installation
and customize your efficiency.
Replace parts, not systems: Every part of a Rinnai Tankless Water Heater is replaceable. Components can be easily exchanged, if needed, versus replacing the entire system.
Save space with a compact design.
Maximum output, minimum space: About the size of a small suitcase, at 18.5”x16”x10”, the Rinnai can be tucked in a small crawl space, attic or basement. These wall-mounted units can be installed on the interior or exterior wall of the home to free up valuable space.
Flexible installation: Small size allows for installation in non- traditional spaces such as crawl spaces and attics, making it perfect for use in any size home, including manufactured and modular homes.
