Rinnai R98LS - Manual (Page 2)

Heat Water Only When You Need It!
T
ankless 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 CO
2
and NO
X
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.
