System AdvantagesRinnai Water Heating

Direct fired heat exchanger means instantaneous waterheating with unlimited supply of hot water on demand.

This system significantly reduces the load on the structurewhich will translate to lower cost in reinforcing the concreteand steel structure.

Wall mounted heater help save more space and only require avery small footprint.

The extra room space from the original system can be give upfor other services and equipment.

There is huge cut down in electrical power consumption bytransferring the heating energy to gas (Clean energy).

Lower storage required due to higher efficient“On Demand” system.

Lesser energy required to maintain the capacity of hot waterstored.

Easy modification by adding extra gas heaters if higher capacityis required for future expansion.

Hot water supply is not interrupted by break down of individualheater due to the multiple module installation.

Only quarterly inspection for cleaning of gas heater filters andpriming of pump is required. Low maintenance of system helpsto cut down labour cost.

What is a Rinnai Manifold Pack?A Rinnai Manifold Pack consists No. of. Infinity continuous flow water heaters plumbed together to allow higher flow rates than a single unit can provide.

What are the key features?• Outlet temperature is preset and remains constant, even when the flow varies

• Peak flow rate cannot be exceeded

• No flow = no gas consumption

• No wasteful pilot lights

• Usually used for dead leg type installations, however ringmain pumps can be fitted if required**Continuous flow water heaters used on flow and return ringmain systems must have correct pipe andpump selection. For further information, please contact your Rinnai Commercial Representative.

What are some suitable applications?Applications include (with suggested temperatures):

• Sporting Club Change Rooms - temperature set at 42˚C or 50˚C

• Shower Blocks in Caravan Parks - temperature set at 42˚C or 50˚C

• Cafés, Restaurants and Pubs - temperatures set at 65˚C

• Hot Water Hoses and Manufacturing Processes - temperature set at 75˚C or 85˚C

What will the SYSTEM offer your application?Energy savings, as there are no tank heat losses, pilot lights and the system only uses gas when in operation.

Endless hot water for applications where there is a peak demand for only a few hours and then either low or no demand for hours, days or weeks at a time.

Pool Heating System

What is A Rinnai Demand Duo SYSTEM?Rinnai Demand Duo is the combination of between 1 and 6 gas continuous flow water heaters with a storage tank. The storage tank allows a short period of high hot water flow rate, greater than the continuous flow rate of the Infinity water heater(s).

How does IT work?Demand Duo is a complete packaged storage hot water system made up of one or more Heavy Duty water heaters with a manifold system, primary pump(s), thermostat and a stainless steel storage tank. The thermostat senses the temperature of the water in the tank, and when it drops below the set point, the primary pump is activated. This flow in turn starts the Rinnai continuous flow Infinity water heater which returns heated water to the tank.

What are some suitable applications?• Hotels & Motels • Apartment Blocks • Student Accommodation• Shower Blocks • Commercial Kitchens • Commercial Laundries

Installations of this type typically have a predictable hot water volume, usually based on number of people living in a particular building either showering, washing or eating, or industrial machines that require regular peaks of water.

Demand Duo are often used on projects on a flow and return system to distribute the water around the building. It should be noted that flow and return systems continually lose heat through the circulation pipework and this adds running costs to the project.

How is the selection made?Refer to the table for selection examples on pg10.

What are the benefits of rinnai Demand Duo?Demand Duo storage hot water systems hold 250 to 315 litres of hot waterper system. This is available where high peak flow rates for short periods oftime are common.

Recovery is matched by selecting the required number of Rinnai Infinity water heaters.The heater(s) can also be mounted many metres (remotely) from the tank.

Note: Extended primary pipe runs must be oversized and/or a primary pump upgrade. Please contact your Rinnai Commercial Representative for further information.

Rinnai Demand Duo systems can also be used instead of Manifold Packs for projects where limited gas supply is available.

What are rinnai Commercial Solar Pre-Heat systems?Rinnai Commercial Solar hot water systems provide solar pre-heated water to the Rinnai Commercial gas hot water systems such as the Manifold Pack or Demand Duo system. It can reduce fuel cost at each building and greenhouse gas emissions.

The system is selected according to the daily hot water demand for the application, the required solar contribution, and what solar zone the system is located in.
