Enhancing the
COMFORTS OF HOME.
With either Rinnai Tankless Water Heaters or
the RH180 Hybrid Tank-Tankless Water Heater,
homeowners can now have more hot water than
they ever thought possible.
The innovation behind our high-efficiency water
heaters provides an endless supply of hot water
wherever and whenever it’s needed – even
for multiple tasks at the same time. Showers
and baths? Laundry and dishes? On-demand
heating means hot water is always available, so
prioritizing activities and scheduling water use is
no longer necessary.
Because they operate on an as-needed basis,
Rinnai Tankless Water Heaters can use up to 40
percent* less energy than traditional systems,
which helps reduce utility costs. This efficient
operation can also contribute to a favorable
HERS rating and optimize LEED certification.
*As based on the average cost to run an electric tank water heater per the DOE Average Energy Costs (doe.gov).
On top of efficiency, our tankless water heaters
feature a copper heat exchanger for unparalleled
quality, durability and safety. And their compact
design offers substantial space savings in the
home.
The RH180 Hybrid Tank-Tankless Water Heater
harnesses the same on-demand tankless
technology coupled with an efficient storage
tank to deliver more hot water with less
recovery time than a traditional tank. And
professionals enjoy time and labor savings
with quick and easy installation using standard
tank connections.
The flexibility and convenience of endless hot
water. The reliability of proven engineering. It’s
everything homeowners need to feel comfortable.
Only from Rinnai.
