Our RUCS models — part of Rinnai’s Luxury Series — offer the highest output of our condensing line of tankless units. They deliver sleek, modern design and a range of features and benefits to fully satisfy the hot water demands of larger homes.
Better Value Than a Tank
Rinnai tankless water heaters last up to twice as long as tanks and have twice the warranty length. Plus, they save energy by heating water only when it is needed. Rebates are also often available.
Technology to Improve Your Lifestyle
Our enhanced control•r™ 2.0 mobile app features timers, programmable schedules and even allows you to remotely put the system into vacation mode when you’re away.
Enjoy the flexibility to choose the unit that works best for your home. Rinnai tankless water heaters are available with natural gas or propane fuel options and can be installed inside or outside.
Reliability You Can Count On
Every Rinnai tankless water heater is individually tested for quality before shipping. Unlike many competitors, Rinnai makes the majority of our key components, allowing for consistent control of quality. That’s why more consumers and businesses choose Rinnai over any other tankless brand.
Never Run Out of Hot Water
With a Rinnai tankless water heater, you’ll never have to choose between taking a piping hot shower, doing a load of laundry, or running the dishwasher. Hot water will always be available when you need it.
Save Valuable Space
The suitcase-sized wall units fit discreetly in small spaces, freeing up more usable living area in your home. Without a tank, your floor will no longer face the threat of a leak from storage of large quantities of water.
