COMMERCIAL WATER HEATING

COMMERCIAL WATER HEATING SOLUTIONS

Nearly 100 years ago, we at Rinnai established a tradition of never settling for

less than the absolute best—a tradition that has grown even stronger today.

Leveraging decades of global commercial water heating experience, Rinnai

Tankless Water Heaters deliver performance and reliability. Precision

engineering allows Rinnai Tankless Water Heaters to produce an endless

supply of hot water to suit even the most demanding applications—from

restaurants to hotels to multifamily residences to schools and more—

conserving energy that can save thousands of dollars in capital, operational

and life cycle costs, while providing redundancy and saving space.

But it’s not just performance that sets us apart. Our commitment to safety,

quality and support has made us the #1 selling tankless brand in the U.S.

and Canada.

From products to service and everything in-between, our dedication to

delivering our absolute best never wavers. We’re stronger than ever, so that

your condence in choosing Rinnai can be too.

WHERE THE DEMANDS ARE GREATEST,

COMMERCIAL SOLUTIONS –

Unlike traditional commercial tank-style water

heaters or boilers, Rinnai Tankless Water

Heaters operate only when needed so they’re

inherently more ecient right from the start.

Plus, as a part of our Tankless Rack System,

modulating units sync up as needed, rotating

and working together to get the job done.

So they’re working less—using minimal

energy—to save you more.

Condensing technology conserves even more

energy, providing an Energy Factor of up to 0.96.

Exact temperature control and other eciency

features all add up to top energy performance

that reduces CO2 emissions and contributes

to LEED® certication for both new construction

and retrot projects.

Condensing appliances use the latent heat of exhaust

to preheat incoming cold water. The colder the

inlet water, the higher the efficiency and the more

condensate is generated.

The chart below demonstrates the eciency that a fully

modulating tankless system can provide. The chart generally

that of a Rinnai Tankless Water Heater.* Peaks represent the



AS THE DAY IS LONG.

Precision-engineered Rinnai Tankless Water

Heaters provide an endless supply of hot water,

without interruption, day in and day out. Rinnai

quality is manufactured rock-solid reliable—you

can safely stake your reputation on it.

Use Rinnai Tankless Water Heaters with or

without a storage tank, or bank multiple units

together in the Rinnai Tankless Rack System

for the added benet of modulating technology

and redundancy.

When one unit is down, another takes over so

that your hot water supply never runs dry, and

your operation doesn’t miss a beat.

Reliable Rinnai Tankless Water Heaters deliver solutions for a full spectrum of

commercial applications—from retrot to new construction and light to heavy.

Because the system congures to your needs, every kind of space, every usage

demand is the perfect Rinnai t—and that makes it easy to do business.

Thanks to our exible venting options and Tankless Rack System, as well

as solutions that are custom designed (with and without storage), you can

use multiple units together to provide anywhere from 15,200 to 4.9 million

BTU—enough to replace even large boilers.

APPLICATIONS:

• Restaurants

• Hotels & Hospitality

• Healthcare Facilities

• Schools/Universities

• Oce Buildings

• Apartment Buildings

Rinnai Tankless Water Heater Case Studies

COURTHOUSE DEMANDS

Situation:

• Multiple showers, sinks, washing machines

and kitchen appliances used at once

• Peak usage hours with high demand; other

periods of time with low use

• Existing system was 2M BTU condensing

boiler and 725-gallon storage tank

Results:

• Installed an interior Rinnai Tankless Rack

System rated 1.2M BTU with Rinnai’s

Common Vent system

• Fully modulating system with a 78:1 turn-down

ratio capable of meeting uctuating demand

• Operated only when needed, saving energy

during low demand

• Experienced less than two hours of downtime

in the transition

MULTI-FAMILY RESIDENCE

Situation:

• High-demand multi-family project with 63 units

• Existing system included two large boilers at

500K BTU each and a 270-gallon storage tank

Results:

• Installed an exterior Rinnai Tankless Rack System

(six tankless water heaters) rated at 1.2M BTU

• Installation on rooftop took only a half day

and was less expensive than what was

originally specified

NATIONAL FULL-SERVICE RESTAURANT CHAIN

Situation:

• Conducted a one-year study to compare tank-

style water heaters to tankless water heaters

in six restaurants across America

• One restaurant from each region installed a

Rinnai Tankless Rack System with four tankless

units, while another from each region installed a

tank-style water heater

Results:

• On average, gas usage was approximately

21% less with tankless

• Each of the three restaurants who used

tankless saw an average energy savings

of $5,820 for the year

• With 1,100 locations nationwide, using Rinnai

Tankless Water Heaters could save this chain

as much as $6.4 million a year

MIDDLE SCHOOL COMPARISON

Situation:

• Two schools with similar hot water

system designs

• One outtted with tank-style water heaters

and one with Rinnai Tankless Water Heaters

Results:

• Rinnai Tankless Water Heaters saved 5.2 to

6.4 cents* per gallon of water used compared

to tank-style units

• Potential annual savings of $1,400

• Energy consumption reduced by more than

70% compared to tank-style units

*Based on a price of $1.60 per therm.

The Rinnai Ultra Series

THE ULTIMATE IN EFFICIENCY.

Delivering our most energy-ecient performance,

the Ultra Series features a unique condensing

design with two heat exchangers to maximize

heating value, as well as a top-down burner to

enhance reliability and durability and reduce

maintenance. The Ultra Series also oers the

most hot water capacity per BTU, with the

ability to support multiple, simultaneous hot

water demands.

Shipped fully assembled in a variety of congurations, the new Rinnai

Tankless Rack System (TRS) arrives ready to install, and ready to impress.

A complete and fully modular solution, TRS features a sturdy, pre-assembled

aluminum rack with multiple Rinnai Tankless Water Heaters already mounted

and connected to each other. Together, the units have enough capacity to suit

a range of light to heavy commercial water heating requirements, replacing

even the largest boilers and tank-style water heaters with one simple, energy-

ecient solution.

Built to your advantage:

Capacity in a whole new form.

• Maneuverability: Fits, fully assembled, through standard 32-inch doorways

and on elevators

• TRS racks come with two to six tankless units per rack, which can be combined

for up to 25 tankless water heaters and provide up to 4.9 million BTU

• Wall-mount or freestanding; outdoors or indoors

• Corrosion-resistant, marine-grade aluminum is strong, but lightweight

• Value engineered from the start—from installation to energy savings

• Modulation technology with turn-down ratios of up to 327:1 to ensure hot

water delivery and eciency

• Use with or without storage tank and/or recirculation loop
