Rinnai Demand Duo System

Each Complete Demand Duo Packaged System includes:

• • One or more Rinnai Heavy Duty Series Water Heaters

• • A Manifold System (where multiple HD Heaters are used)

• • Primary Pump(s)

• • Thermostat

• • 205 or 315 Litre Stainless Steel Storage Tank

The Thermostat starts the pump when the temperature drops below the required heat. This in turn fires off the HD Water heater(s).
