The Rinnai LS Series tankless water heater

is a state-of-the art, energy-efficient water heating system that uses a gas-powered heat exchanger to heat water. The Rinnai LS is the perfect choice to supply all your hot water needs. And unlike traditional tank systems, the Rinnai system can deliver hot water to multiple water sources simultaneously at a constant user-set temperature.

Compact in size, LS Series interior wall-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.

Rinnai models are available in natural gas or propane gas units that deliver up to 9.8 gallons per minute (GPM) of continuous hot water with 15,000 to 237,000 BTU heating capacity (R98LS models). They feature a direct energy-saving electronic ignition. No more energy-wasting pilot lights. Interior mount units require no indoor make-up air and vent directly to the outside atmosphere.

With the newly designed commercial-grade exchanger, 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.
