What is a Multi-Head Split System?

‘Multi-head’ refers to the system of having multiple indoor split units throughout a home that run from a single outdoor unit. Each indoor unit heats and cools their respective room(s) while the outdoor unit (usually installed at the side or back of the house) runs the multiple indoor units.

Multi-head air conditioners are ideal when there is limited space for multiple outdoor units. Multi-Head Systems also allow for individual control of the air conditioning in each room. This optimises comfort levels as each room can be set to your desired temperature. Multi-Head Systems can also mean reducing your electricity bills because you’ll only heat and cool the rooms in use.

The multi-head system you choose will depend on how many rooms require heating and cooling. Up to 9 indoor units can connect to a single outdoor split system unit. At Coldflow we have a huge range of the best brands to choose from.


How Do Multi-Head Split Systems Compare?

Traditional Split Systems have a matching outdoor unit for every indoor unit; given that every home has multiple rooms, having an outdoor unit for every indoor unit would take up a lot of space and power consumption – that’s where a Multi-Head system comes in.

With a Multi-Head system, you can have 2 or more indoor units connected to 1 outdoor saving you valuable space, and future servicing costs.

How a Multi-Head Split System works compared to a standard Split System:



How Do Multi-Head Split Systems work?

Multi-Head Split Systems use the same technology as normal Split Systems. They work by having half the system (called a condenser) outside the home, and the other half (called the fan coil, or internal unit) inside the home.

When cooling, the warm air from inside the room is taken in by the fan coil and removed, resulting in cool air recirculating back into the house. While reverse cycle allows for the heat pump to run in reverse to provide heating during cold days.

What Are The Running Costs With Split Systems?

One of our recommended brands for Multi-Head Split Systems is Mitsubishi Electric. For a Mitsubishi Electric MXZ Series 7.1KW System, installed in 2x small bedrooms, and 1x lounge room providing regular heating & cooling during the winter and summer periods, the annual running cost would be measured at $702.90.


*Data is based on: 2016 Victoria Energy Tariff of 32.1 c/kWh, using a Mitsubishi Electric Multi-Head MXZ-4e71vad/msz-ge25vad collected from Sustainability Victoria’s Energy Consumption and Running Costs website. Usage times were set on average to 4 months of heating, and 2 months of cooling based on 7 hours a day. Actual running costs are affected by many factors including climate and insulation; this data should only be used as a guide and does not guarantee your individual running costs will reflect these results.

Reducing Multi-Head Split System Running Costs

It doesn’t take much to reduce your running costs. Depending on the model you purchase, and it’s respective star rating will determine how much you can save annually. However looking beyond the initial cost to how you use your Multi-Head Split System can help as well.

Tips For Using A Multi-Head Split System

Best Tip! Set the thermostat between 24C and 26C for cooling. Every degree lower in summer
will increase the running costs by around 10%.

  • Use the economy setting if your multi-head split system has one and regularly service your air conditioner.
  • Keep the sun’s heat out by closing curtains and external blinds during the day. Close windows and doors to areas being cooled when the split system is running.
  • When the multi-head system is switched off and its cooler outside, open doors and windows to let the cool air in.
  • Insulate your home to keep the heat out in summer and in during winter.
  • Dress to suit the weather conditions.

    This is my second system that Coldflow have installed and I'm very happy with the result.

  • Again, very happy with the service

    I was extremely happy with the service provided by Coldflow.
    I had a ducted cooling system installed. The team turned up on time and completed the job the same day. The guys were courteous and completed the job with a minimum of fuss and disruption. The workmanship was excellent and all ducts were located as per our agreement. They placed drop sheets wherever required and cleaned up after completion. Again was very happy with the service provided by all the crew.
