Heat Water Only When You Need It!

Tankless water heating is the wave of the future – available to you today.

You’ll enjoy up to 40% energy savings, endless hot water, and significant

space savings – plus a typical life span of 20 years or more in residential

applications. And this “green” technology produces less CO2 and NOX than conventional gas or electric tank water heaters.

You see, Rinnai tankless water heaters use natural gas or propane gas to heat water only when needed. When water flow is detected, the Rinnai begins heating water as it passes through its copper heat exchanger. The design of the unit allows it to capture up to 84% of the heat energy, making it highly efficient and cost effective.

When the demand for water ceases, the tankless unit shuts down and uses no energy – a revolutionary advantage over inefficient tank-style heaters. More efficient when it’s on, and off when it’s off, the Rinnai tankless water heater is the ultimate choice in today’s world of high energy costs and environmental preservation.

Additionally, your Rinnai is supported by the most extensive group of professionals in the business. Our nationwide network of more than 80,000 registered dealers and factory-trained installers ensures a trouble-free installation and reliable after-the-sale support.

Enjoy Endless Hot Water

Tankless water heating is one of the few energy-saving technologies that actually improves the quality of your life. You’ll delight in endless hot water – for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches your life. Plus, our digital controllers give you precise control of the output water temperature for the ultimate in comfort and safety.

Save Space

Traditional tank water heaters can take up to 16 square feet of valuable floor space. But your Rinnai unit – only about the size of a carry-on suitcase – can be installed on virtually any wall inside or outside of your home or building. The compact design affords you almost limitless installation options, so you can strategically locate the unit for maximum performance and energy efficiency.

Contemporary design

Experience a never-ending supply of fresh hot water – and a sleek, sculpted water heater design that reflects the innovative technology within. Introducing the Rinnai LS Series, a whole new line of tankless water heaters that afford you the very best of both form and function. With their attractive silver finish, Rinnai LS Series units are available in interior and exterior models, giving you virtually unlimited flexibility to install your unit wherever you choose.

Perfect for Any Home

The remarkable combination of design and performance makes the LS Series the perfect choice. Whether you’re building a spacious new home – complete with luxurious spa bath and body spray system – or remodeling your older home, Rinnai LS units can be used individually, in pairs, or in banks of three or more to supply all your hot water needs.

LS Series interior-mount units can be placed in any room – no need to hide them in closets or utility rooms – and vent directly to the outside. Exterior units require no additional venting and can even be installed in a recessed enclosure, then painted or textured to match the exterior of your home for a clean, inconspicuous appearance.

Improved performance and Longevity

Whichever LS unit you choose, you get the benefit of a newly designed, commercial-grade heat exchanger for optimum durability. In fact, the same LS unit can be used for both residential and commercial applications. Homeowners get the reliability of commercial-grade construction and an industry-leading, 12-year limited warranty, and commercial customers get lower cost and wider availability of units.

Accessories

Rinnai’s line of digital controllers allows you to set water temperature precisely for multiple locations in your home, analyze and troubleshoot the water heater, and even automatically fill your bath to a pre-set temperature and volume. An available wireless controller is perfect for retrofits where pulling a wire through the wall is impractical. (Note: the

MC-91 controller comes standard with all LS units.)

Flexible Installation

Choosing a mounting location depends on your taste, your home or building, and your location. Install your Rinnai tankless water heater inside, outside, in a garage or laundry room or virtually anywhere else.

For interior installation, Rinnai units use a concentric venting system – a single vent assembly featuring an inner, metal vent for exhaust gases and an outer PVC or metal tube for bringing combustion air from outdoors. The result: a direct-vent, sealed-combustion system that offers optimum safety, performance and ease of installation.

Exterior units can be installed in a recessed enclosure, flush with the outer wall, then painted or textured to match your home’s panel or brick siding.

And if you need more than one unit for your larger home, spa or body spray shower, Rinnai’s EZ Connect feature allows you to link two units with a simple cord. For even larger applications, your installer can place multiple units in parallel.
