Tankless Water Heaters

Creating A Whole New Way To Think About Water Heating

An endless supply of hot water, whenever you need it—even for multiple tasks at the same time. Tankless Water Heaters revolutionize comfort, energy efficiency and convenience.

Enjoy fresh, hot water at your fingertips. 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 Condensing Tankless Water Heaters were the first to use a unique Concentric Polypropylene Venting System – a single vent assembly option featuring an inner tube for exhaust and an outer tub for fresh air from outdoors. The result is a direct-vent, sealed combustion system that offers optimum safety and performance. In addition to Concentric Polypropylene, Rinnai offers a venting solution for PVC/CPVC with the new Ubbink Concentric to PVC Twin Pipe Adaptor. Multiple venting options allow for an installation of total convenience.

Thanks to the design and technology, Rinnai Tankless Water Heaters are the ultimate choice for energy cost savings and environmental preservation. 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.

A Rinnai Tankless Water Heater is about the size of a carry-on suitcase, and can easily be mounted on virtually any interior or exterior wall, saving you up to 16 square feet of valuable floor space or extra storage. And, no holding tank means fresh, clean hot water every time.

While conventional tank water heaters have an average service life of less than 10 years, Rinnai Tankless Water Heaters last up to 20 years* and are backed by an industry-leading warranty.

*Based on DOE ENERGY STAR® lifecycle estimates, tankless water heaters can last up to twice as long as traditional tank units.
