Benefits of the Daikin Nexura include:

  • 500% efficient:  The most efficient radiant heating heat pump in Australia.
  • Can cool as well as heat: The Nexura is just like a reverse cycle AC; if you get hydronic heating, should you want to cool your house, you'll also need to buy air conditioners.  The Daikin Nexura saves you this cost which can be up to $10,000 for a large home.  
  • No heating loop losses: Hydronic heaters lose up to 20% in their heat loop.
  • Superior zoning: This allows you to heat or cool just the parts of the house you want to, saving you money on heating bills. 
  • Low thermal inertia: compared to hydronic, which takes up to 30 minutes to reach its nominal heat loop temperature. 
  • Lower running costs: Higher efficiency means lower energy bills.  
  • Standard servicing: Much cheaper to service than a conventional hydronic system.
  • Radiant Mode: At the touch of a button, Nexura's aluminium  front panel warms up just like a traditional radiator. The result is warmth from radiant heating, like from a fireplace, which many people prefer.  
  • Air Purification:  Fitted with a titanium apatite deodorising air purification filter, that traps microscopic particles, decomposes odours and even deactivates bacteria.

If you think your Daikin Nexura needs cleaning/maintenance, take a look below for do's and don'ts:

  • Wait for a while before cleaning the unit after RADIANT operation. The surface temperature of the radiant panel may be high immediately after the operation.
  • Before cleaning be sure to stop operation and turn the circuit breaker off (if unsure seek expert advice).
  • Do not touch the aluminium fins of the indoor unit, they may be hot.

For cleaning, do not use any of the following materials:

  • Hot water above 40°C.
  • Benzine, gasoline, thinner, other volatile oils.
  • Polishing compound.
  • Scrubbing brushes, or hard bristles.
Daikin Nexura Care and Cleaning


The air conditioner stops generating air flow during operation.

Once the set temperature is reached, the airflow rate is reduced and operation is stopped in order to avoid generating cool airflow (during heating) or in order to keep the humidity from rising (during cooling). Operation will resume automatically when the indoor temperature rises or falls.

Unit does not start immediately when “ON/OFF” button was pressed, soon after operation was stopped or when a new mode is selected.

The delay in starting in these situations is to protect the air conditioner from wear and tear. You should wait for about 3 minutes before trying these options. 

The HEAT operation stops suddenly and a flowing sound is heard.

The outdoor unit is taking away the frost. The HEAT operation starts after the frost on the outdoor unit is removed. You should wait for about 4 to 12 minutes.

The flap does not start swing immediately.

The air conditioner is adjusting the flap position. The flap will start moving soon.

The radiant panel surface temperature doesn't feel very hot

During RADIANT1 or RADIANT2 operation, the surface temperature of the panel will be about 55°C at maximum; this is the normal condition.

If your Daikin Nexura outdoor unit emits water or steam, here are some of the reasons this might be the case:

In HEAT or RADIANT operation

The frost on the outdoor unit melts into water or steam when the air conditioner is in defrost operation.

In COOL or DRY operation

Moisture in the air condenses into water on the cool surface of outdoor unit piping and drips.

Your Daikin Nexura will make certain noises as part of its normal operation (if you hear noises outside this list you may need to take action or contact your local AC mechanic): 

The following is a list of noises you may hear that are not a cause for concern:

A sound like a flow of water:

  • This sound is generated because the refrigerant in the air conditioner is flowing.
  • A pumping sound of the water in the air conditioner it is heard when the water is pumped out from the air conditioner in cooling or drying operation.
  • The refrigerant flows in the air conditioner even if the air conditioner is not working when the indoor units in other rooms are in operation, which may sound like a flow of water. 

Blowing sound:

This sound is generated when the flow of the refrigerant in the air conditioner is switched over.

Pinging sound:

This sound is generated when the size of the air conditioner slightly expands or shrinks as a result of temperature changes.

Clicking sound during operation or idle time:

This sound is generated when the refrigerant control valves or the electrical parts operate.

Clopping sound:

This sound is heard from the inside of the air conditioner when the exhaust fan is activated while the room doors are closed. Open the window or turn off the exhaust fan.
