Life is Better With Rinnai Tankless

Rinnai’s super high-efficiency models offer sleek design, maximum output and an array of features ideal for the hot water demands of large homes.

Energy Efficiency

Rated by a Uniform Energy Factor (UEF), tankless water heaters are a highly efficient hot water appliance and ENERGY STAR® certified units offer additional energy saving benefits.


Tankless water heaters are easier to repair than tanks, often eliminating the need to replace the unit. And many offer extended, comprehensive warranties.


Accessories like room motion sensors and push-button water demand are available to help make hot water instantly available when it’s needed.

Compact Size

Tankless water heaters are about the size of a carry-on suitcase, so they can fit in small spaces like closets, cabinets, and mud rooms.

Unlimited Hot Water

Because your water is continuously heated as needed, you’ll never have to choose between taking a hot shower, doing a load of laundry, or running the dishwasher.

Wi-Fi Capable

Wi-Fi technology allows certain water heaters to be monitored and controlled (scheduling, recirculation, and more) via smartphone or voice-controlled device.

Rinnai Tankless Vs Water Heater Comparison

SUPER-HIGH-EFFICIENCY TANKLESS STANDARD TANK Cold Water enters inlet pipe only when hot water is required. Gas ignites heat exchangers, which heat the water. Heater will adjust flame output as needed to ensure a temperature set point is maintained. When no more hot water is required, system shuts off until hot water is needed again. Large tank requires more installation space and management. Water in tank is heated and reheated to maintain desired set temperature regardless of usage or demand. During times of heavy use, water can be depleted, causing delays in hot water supply. In the event of tank failure, large amounts of stored water can cause extensive damage to the home. During times of heavy use, water can be depleted, causing delays in hot water supply

“I have a Rinnai tankless water heater in my own home and wouldn’t accept anything less.”

-Jim Crawford, professional plumber of 30 years
