The Rinnai DINLR14Z72 / DONSR14Z72 is a high static reverse cycle ducted air conditioning system designed for larger homes, open-plan living areas, and multi-room properties that require strong airflow and discreet whole-home comfort. Its slimline indoor unit fits neatly into the roof cavity, while the inverter compressor delivers efficient heating and cooling throughout the year. With 14.2kW cooling and 17.3kW heating capacity, this model is ideal for large homes, open-plan spaces, offices, and areas around 60–100m² depending on insulation and layout. It can modulate from approximately 5.6kW to 16.1kW in cooling mode and from 5.8kW to 19.0kW in heating mode for more stable temperatures and improved efficiency.

Key Features & Benefits

High Static Pressure Performance

The system supports a maximum external static pressure of up to 200Pa, making it suitable for long duct runs, multiple outlets, and larger zoned ducted systems. High airflow of approximately 1075 litres per second helps maintain even air distribution throughout the home.

Single-Phase Power Supply

This model operates on standard 220–240V single-phase power, making it suitable for most residential properties without requiring a 3-phase electrical upgrade. Maximum input current is approximately 26 amps with a recommended 32-amp circuit breaker.

Advanced DC Inverter Technology

Rinnai’s 3D DC inverter technology automatically adjusts compressor speed to maintain more consistent temperatures while helping reduce running costs. The system is designed to be up to three times more efficient than traditional electric heating methods.

Strong Airflow Performance

The large-capacity indoor unit is designed to deliver strong airflow across multiple rooms and larger open-plan areas. Its high static design helps maintain even comfort throughout the property, even with long duct layouts.

Slimline Indoor Unit Design

The indoor unit measures approximately 1200mm wide, 625mm deep, and 380mm high, allowing it to fit into many residential roof spaces while remaining concealed from view. Only discreet ceiling diffusers are visible inside the home.

Quiet Operation

Indoor sound pressure levels are approximately 49dBA on high fan speed, 45dBA on medium, and 42dBA on low speed. The outdoor unit sound pressure level is approximately 61dBA at 1 metre.

Optional Wi-Fi and Zoning Compatibility

The system includes a wired programmable controller and supports optional Wi-Fi connectivity for remote operation. It can also be configured for zoned ducted systems to independently control airflow to different areas of the home.

Wide Operating Range

The unit can operate in outdoor temperatures from -15°C to 50°C in cooling mode and from -15°C to 24°C in heating mode, making it suitable for Australian climate conditions year-round.

R410A Refrigerant

The system uses R410A refrigerant and supports pipe runs up to 50 metres with a maximum vertical separation of 25 metres between indoor and outdoor units.
