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 EZConnect™ feature allows you to link two units with a simple cord. For even larger applications, your installer can place multiple units in parallel. |
