What is a Multi-Head Split System?

‘Multi-head’ refers to the system of having multiple indoor split system 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.

Frequently Asked Questions About Multi Head Split System Airconditioning

How Do Multi-Head Split Systems Work?

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 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 Multi Head 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.

Multi head split system running costs diagram
How a Multi-Head Split System works compared to a standard Split System
*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 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 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 split 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.

Why Choose Multi Head Split System?

Multi-Head Split Systems are an economical solution for cooling lots of different rooms. Multi-head air conditioners are relatively simple to install, and the installation process can be incorporated to your renovation or building project. Building occupants can adjust the heating/cooling in their own room. It is an ideal choice for large homes, office buildings, and multi-residential premises.

Very likely, your team arrived on time. They worked quickly and efficiently, plus they were very friendly. They left our house as they found it , clean and tidy. Just one thing they left behind a piece of equipment which I'm sure they can use. It is no use to us, so it would be a shame to throw it out. Many Thanks.

Courteous serviceman with professional attention to his job. Easy to book. Fair cost for service rendered. (A competitor outfit required pre-payment for the service call, about $150, and then quoted a price of $2,000 for the same work. He was quickly escorted off the premises.)

I have already recommended Coldflow to two other friends/family who are considering AC upgrades. With this installation, the only glitch was the rescheduling due to our household being close contacts for COVID. Once that was out of the way, it all went smoothly.
