The chart below demonstrates the eciency that a fully modulating tankless
system can provide. The chart generally shows the gas usage of a traditional boiler
compared to that of a Rinnai Tankless Water Heater.* Peaks represent the tankless
unit meeting user demands, and valleys represent saved energy in between.

Maximum Performance
that Lasts Longer
Easy installation, superior performance and longer life mean there
has never been a better time to switch from traditional tanks to the
consistency and eciency of Demand Duo H- and R-Series solutions.
How Demand Duo Works
Water heats in the tankless unit rather
than inside the tank, providing:
• Zero thermal stress on the tank
• More hot water capacity, since tank only
holds two magnesium anode rods
• Easy, cost-eective tankless maintenance
versus replacing an entire tank every few
years
• Ideal for emergency replacement; installs like
a tank but over 100 lbs lighter than most tanks

Fox Run Apartments | Multi-Family
THE SMARTER WAY TO DO HOT WATER
Fox Run Apartments in Cincinnati, OH has 240 living units across 19 buildings.
The owner, BRG Realty, dealt with rising electrical rates and soaring maintenance
costs to run and repair their existing electric tanks that serviced 12 apartments per
building. By converting to Demand Duo condensing units in each building, BRG has
improved renter satisfaction and netted over $20,000 in combined energy and
maintenance savings in the first year. “The maintenance is lot easier with Demand
Duo and we no longer have to worry about constantly replacing heating elements
and fuses, said BRG Maintenance Director Mike Markus. “The reliability of Demand
Duo has been a great deliverable to BRG and our residents.”

SAVINGS FROM DAY ONE
Located in Kelowna, Canada, this campus of 9,120 students recently installed 3
Demand Duo 2V commercial hybrid water heaters in a residence hall that services
72 living units equipped with 2 bd/1ba and a kitchen. With 2 tankless units attached
vertically to a 119-gallon tank, the Demand Duo 2V provides more redundancy, 551
GPH and better serviceability than other traditional water heating systems . “The
Demand Duo’s are 12-18% more efficient than most of the commercial tanks we
encounter plus they have more than 2X the warranty” said Brent Watson, Owner
of Vision Mechanical who did the installation at UBC Okanogan, “and that makes
them ideal to meet the extreme hot water demands of a university residence hall.”
Crowne Plaza Atlanta – Midtown | Hospitality
WORRY-FREE INSTALLATION
Rinnai’s total turnkey solution for this 432-room hotel delivered immediate savings
on energy costs in November 2019. Managing all aspects of design, logistics,
installation and billing, Rinnai replaced two aging, increasingly inefficient dual-
burner boilers with 10 Demand Duo 2 Hybrid Water Heating units. Now, Demand
Duo’s 97% thermally efficient system serves all the domestic hot water needs
for the property, fitting in the same footprint as just one of the boilers and freeing
up space in the mechanical room. Additionally, two Demand Duo 2 units in the sub-
basement supply all the hot water needs of the hotel’s commercial kitchen
and laundry.

TANKLESS RACK SYSTEMS

Now you can harness all the benefits of tankless water heating
technology, pre-assembled and ready to replace the boiler in
your existing or planned boiler and storage tank domestic water
heating system.
Built with superior quality and reliability, Rinnai’s Tankless
Rack System
TM
(TRS) oers the perfect BTU upgrade of an
old-style domestic water boiler that is reheating storage tanks.
On retro-fit applications, oftentimes you can keep your existing
tank and pump and simply replace with the lower-cost and
better-performing TRS.
The TRS installs in place of an old-style boiler and provides
built-in redundancy by banking individual Tankless Water
Heaters to ensure your hot water supply keeps flowing even
if a unit is down. The TRS comes standard with our new
condensing CX199 Tankless Water Heater that boasts 97%
thermal eciency and a heat exchanger built for the demands
of commercial applications.

Flexible installation is another TRS strong suit. It fits
through a standard 32" doorway, has various venting
options including PVC and the Rinnai Common Vent
system, and can be mounted indoors or outdoors, either
floor-standing or wall-mount.
By oering a significantly lower upfront capital investment
and reduced annual maintenance costs, the overall cost of
ownership can be lower vs. the same BTU boiler. Couple
that with the Rinnai reputation for unsurpassed quality and
technical support — plus the added benefit of having the
Rinnai Commercial Solutions Team help with free sizing and
application engineering — and the TRS is the business-
friendly replacement for even the largest boilers.

DEFINITIONS:
Tank size: capacity of water in gallons inside storage tank as stated
by manufacturer
Recovery pump: pump that will circulate water from tank to
TRS during recovery period
Recovery Flow Rate: flow rate in GPM at which volume inside tank
is being recovered
Recovery GPH: the water heater’s ability to replenish hot water
as it’s drawn from the tank
Recovery eciency: the ratio of energy delivered to the water to the
energy content of the fuel consumed by the water heater
First Hour Delivered (Gal): usable volume of water that can be
drawn in one hour, determined using the following formula: First Hour
Delivered (Gal) = Recovery GPH + tank capacity x 0.70
Temperature rise: temperature dierence in °F between the TRS set
point and the incoming water temperature
Note: This chart should be used only when the existing or specified system is known. Select TRS model to the left. Use existing or specified storage tank with TRS selection. Reference
chart above for recovery GPH performance. To calculate “First Hour Delivered” add 70% of existing or specified tank volume to recovery GPH.
Multiple configurations available. Reference TRS Installation Manual. TRS models are free-standing units; TRW models are wall-mount units.

Common Venting | Direct Vent - Polypropylene
Use the Rinnai Common Venting System which uses
Polypropylene PP – a more reliable venting material for the job and
able to withstand exhaust temperatures up to 230° F.
• Clean, easy, cost eective installations that require less labor
• Fewer wall of roof penetrations
• Vent lengths up to 150’ with 8 TWH units
• Easy push fit joints – no cement or glue required
• In-line or back-to-back installations; horizontal or vertical termination
• More venting options than ever before for indoor installations
