Get in the Zone

Zoned heating systems are a big investment, but can pay off over time, by keeping heating costs down while making sure your home stays comfortable.

Get in the Zone

Over the winter months, many households see a spike in their energy bills due to increased heating requirements. One effective strategy to minimise these expenses is implementing zoned heating systems. Zoned heating allows homeowners to control the temperature in different areas or "zones" of the home independently, ensuring that energy is used efficiently and only where needed.

Here’s an in-depth look at how you can minimize your energy bill expenses with zoned heating during the winter months.

Understanding Zoned Heating

Zoned heating involves dividing your home into different areas, each of which can be heated separately. This can be achieved through various methods, including:

  1. Ducted Heating Systems with Zone Control: These systems use a central unit to heat air and distribute it through a network of ducts. Zone control dampers installed within the ducts can open or close to direct heated air to specific areas.
  2. Multi-Split Systems: These are air conditioning systems with multiple indoor units connected to a single outdoor unit. Each indoor unit can be independently controlled, allowing for different temperatures in different rooms.
  3. Radiant Floor Heating: This system heats the floor surface, and zones can be created by installing separate loops for different areas of the home, each with its own thermostat.

Benefits of Zoned Heating

1. Energy Efficiency

By only heating the rooms that are in use, zoned heating systems reduce the amount of energy required to keep your home comfortable. This targeted approach ensures that no energy is wasted on unoccupied areas, leading to significant savings on your energy bill.

2. Enhanced Comfort

Different family members often have varying temperature preferences. Zoned heating allows each zone to be set to a comfortable temperature, catering to individual needs without compromising on energy efficiency.

3. Extended Lifespan of Heating Equipment

Since zoned heating systems don’t need to work as hard to heat the entire house at once, they experience less wear and tear. This can extend the lifespan of your heating equipment, reducing the need for frequent repairs or replacements.

Practical Steps to Implement Zoned Heating

1. Assess Your Home’s Layout

The first step in implementing zoned heating is to assess the layout of your home. Identify areas that are used frequently and those that are seldom occupied. Commonly used zones might include living areas, kitchens, and bedrooms, while guest rooms, basements, or storage areas might not need regular heating.

2. Install Programmable Thermostats

Each zone in a zoned heating system should have its own programmable thermostat. These thermostats allow you to set specific temperatures for different times of the day, ensuring efficient energy use. For instance, you can program the living room to be warmer in the evenings when the family gathers and cooler during the night when it’s not in use.

3. Upgrade to a Zoned Heating System

If your current heating system doesn’t support zoned heating, consider upgrading to one that does. For ducted systems, this might involve installing zone control dampers and a compatible control panel. For multi-split systems, it may mean adding more indoor units. Consult a professional HVAC technician to determine the best solution for your home.

4. Seal and Insulate

Proper sealing and insulation are crucial for maximizing the efficiency of zoned heating. Ensure that doors and windows are well-sealed to prevent drafts. Insulate walls, floors, and ceilings to reduce heat loss, allowing each zone to maintain its temperature with less energy.

Maximizing Savings with Zoned Heating

1. Smart Use of Thermostats

Take full advantage of programmable thermostats by setting lower temperatures for unoccupied zones or when heating isn’t needed, such as when everyone is at work or school. You can also use the thermostat’s scheduling features to gradually increase the temperature before you wake up or return home, ensuring comfort without excessive energy use.

2. Utilize Natural Heat

Make the most of natural sunlight to warm your home during the day. Open curtains and blinds in sun-facing rooms to let in heat and close them at night to retain warmth. This can reduce the workload on your heating system and enhance the efficiency of your zoned heating setup.

3. Regular Maintenance

Keep your heating system running efficiently by scheduling regular maintenance checks. Clean filters, check for leaks in ductwork, and ensure that all components are functioning correctly. Well-maintained systems perform better and use less energy, leading to lower bills.

4. Educate Household Members

Ensure that everyone in your household understands how to use the zoned heating system effectively. Encourage them to close doors to unused rooms and not to tamper with thermostat settings unnecessarily. Collective effort can significantly enhance the system’s efficiency.


Zoned heating is a practical and efficient way to minimize energy bill expenses during the winter months in Australia. By heating only the areas of your home that are in use, you can enjoy enhanced comfort and significant energy savings. Whether upgrading your existing system or installing a new one, the benefits of zoned heating make it a worthwhile investment. Implement the steps outlined above to optimize your home’s heating efficiency and reduce your energy bills this winter.
