Rinnai Introduces Dual-Use Tankless Water Heaters
Rinnai Corporation has recently introduced its LS Series line of high-output, high-efficiency tankless water heaters that can be used for residential and commercial applications — a first in the industry.
Unlike other tankless water heaters, the LS Series offers home owners the reliability of a commercial-grade heat exchanger. For home owners and contractors, this means that the same unit can be used for either domestic hot water or domestic hot water plus space heating.
The heaters have a sleek, sculpted design and come with a 12-year warranty. The R94LSi has a maximum input of 199,000 BTUs and maximum output of 9.4 gallons per minute. A smaller heater is available with 7.5 gpm outflow.
Available in interior and exterior models, Rinnai’s LS Series has an attractive, powder-coated silver finish with available matching pipe covers. The manufacturer says that the resulting installation is the sharpest in the industry.
For interior installations, Rinnai uses 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 is a direct-vent, sealed-combustion system that provides optimum safety, performance and ease of installation.
The exterior units require no additional venting and can even be installed in a recessed enclosure, then painted or textured to flush with the outer wall.
Tankless water heaters can be worth water-efficiency points for builders certifying their projects through NAHB Green, the NAHB National Green Building Program.
In addition to being extremely efficient, the easy installation and low maintenance of tankless water heaters make them ideal for builders working in the 50+ housing market, Rinnai says.
“With many boomers moving into smaller homes that require less maintenance, Rinnai tankless water heaters can provide the ideal combination of performance and value, fueling popular amenities such as body spray/massage showers, soaking tubs and walk-in seating tubs,” according to the manufacturer. “And with no tank to rupture, Rinnai tankless water heaters leave traveling 50+ home owners with peace of mind.”
For those building off the main natural gas line, Rinnai tankless water heaters can also be fueled by clean and efficient propane.
The Propane Education and Research Council (PERC) has a number of resources — including a green online course, “Green Water Heating With Propane: Retrofitting From Electric” — to introduce 50+ builders on the benefits of building with propane.
With an American headquarters in Peachtree City, Ga., Rinnai Corporation is a member of the National Council of the Housing Industry (NCHI) — The Leading Suppliers of NAHB.
Based in Washington, D.C., the Propane Education and Research Council is also an NCHI member.
