You spend your business day multi-tasking – why shouldn’t your commercial hot water system do the same? Introducing the Demand Duo Commercial Hybrid System – the perfect solution for direct replacement of most traditional and high efficiency commercial tanks. And, only Rinnai backs it’s nearly 100-year reputation of quality and reliability with a 6-year HEX/Tank warranty. The all new Rinnai Demand Duo is a master multi-tasker you’re sure to admire.

Demand and SupplyCombining the on-demand, continuous supply technology of tankless with an energy efficient and durable 119-gallon storage tank, the Demand Duo provides more water-heating capacity than a traditional tank in the first hour. The result: Hot water is available to keep pace with demand – from short-period, high-spike draws, to a supply that’s ready to go the distance, day in and day out.

Ultimate EfficiencyEquipped with the all new C199 Tankless Water Heater which is Commercial ENERGY STAR® certified, has 96 percent thermal efficiency, 199,000 BTU, fueled by either Natural Gas or Propane, the Demand Duo produces consistent water temperatures for predictably smooth business operations. Optimum performance is achieved by efficient tank recovery methods so you can count on having hot water even during reheat cycles.

Peace-of-Mind MonitoringThe effort to keep hot water availability and business uptime high doesn’t stop with the hybrid system itself. The Demand Duo can also tie into a building management system with the DPS / MIS accessory, sending alerts when the system needs attention. In addition, the maintenance alert system on the Rinnai built-in controller provides peace-of-mind monitoring protection to put the efficiency and performance of your hot water on cruise control.

Strength In NumbersWith the ability to install multiple Demand Duos together, we create redundancy back up that keeps hot water flowing – and your business going.

MAXIMUM EQUIVALENT VENT LENGTH

** Exhaust must terminate vertically.*** Maximum equivalent vent lengths are specific to the fuel type of the tankless water heater. Use of elbows in installation will reduce the maximum vent length. It is imperative when performing equivalent vent length calculations, refer to the Installation Manual and any applicable technical bulletins.

Common venting means significantly fewer wall or roof cuts, less labor, and longer vent lengths with single-unit venting. Along with our existing common venting options, Rinnai has six NEW common vent solutions including:

• Room Air for the U.S. and Canada**• Direct Vent in different plane configurations (exhaust must be vertical) for the U.S. and Canada**• Direct Vent for Canada

In a common vent room air configuration, multiple unit installations use the air in the room for intake air and therefore require only one vent penetration for the exhaust. This means one less wall or roof cut saving time and money for system installation. Room air can be used only in applications that utilize the approved Rinnai common vent method.

For more flexibility, common venting can now be done in different plane configurations with a vertical exhaust vent and horizontal air intake.

Both of these new solutions use Rinnai’s existing 8” PPtl venting material and are now approved with 8” PPs venting for markets that require ULC S636 for venting.

SINgLE-UNIt vENt SoLUtIoNSThe dual venting configuration on the top allows for maximum flexibility for installers and dealers — one Concentric vent or two PVC/CPVC pipes can be used for venting.
