Installing ducted heating requires the setup of a central unit that distributes either warm or cool air throughout your home via ducts installed in the ceiling or floor. Each room receives airflow through strategically placed vents, while temperature control is managed through a wall-mounted controller, allowing for comprehensive climate management across the house. In Melbourne, many homeowners prefer electric reverse cycle ducted heating, a highly efficient system that provides warmth in winter and cooling in summer through the same vents. Alternatively, gas ducted heating is also available, and this guide offers a thorough comparison of both systems.
This guide presents an extensive overview of the ducted heating installation process, addressing essential elements such as system sizing, zoning, ductwork, the outdoor unit, and what to expect on the day of installation. We will also explore the operating costs associated with gas systems, the Victorian Energy Upgrades (VEU) rebate relevant for switching to electric systems, and important questions to ask any installer before making a commitment.
- The Australian Government’s energy.gov.au indicates that reverse cycle air conditioners boast efficiency ratings ranging from 300% to 600%.
- Energy.gov.au further mentions that ducted reverse cycle systems operate more economically than gas heating systems.
- Most installations are typically completed in a single day; however, larger homes or complex duct layouts may require an additional day.
- The VEU rebate applies when replacing an old gas heater with a qualifying reverse cycle system.
Which Ducted Heating Options Are Most Suitable for Your Home?
In Melbourne, there are two primary types of ducted heating systems available for homes, with an option to add cooling to an existing gas system.
- Electric Reverse Cycle Ducted Heating and Cooling. This system consists of both an outdoor and an indoor unit, working in tandem to heat or cool your entire home through a unified network of vents. This is the most commonly installed system, with further information available on our ducted reverse cycle air conditioning page.
- Gas Ducted Heating. A gas furnace generates warm air, which is circulated through the ducts by a fan. Although gas ducted heating installations are still performed, many homeowners in Melbourne are opting to transition away from gas rather than install new gas heaters.
- Add-on Cooling for an Existing Gas Heater. If your gas ducted heater is relatively modern, you can integrate an add-on cooling system that utilises the same ducts and controller to provide cooling.
If your gas heater is outdated, frequently requires repairs, or incurs high operational costs, consider upgrading to an electric reverse cycle ducted system. This solution offers both heating and cooling in one installation. For more detailed insights on replacing gas ducted heating with electric heating, refer to our comprehensive guide.
How Does Reverse Cycle Ducted Heating Operate?
Reverse cycle ducted heating functions by transferring heat rather than generating it. According to the Australian Government’s energy.gov.au heating and cooling guide, reverse cycle air conditioners can convert one unit of electrical energy into three to six times more heating or cooling energy, achieving efficiency ratings between 300% and 600%. In contrast, an electric bar heater converts one unit of electricity into one unit of heat.
During winter, the outdoor unit extracts heat from the surrounding air and transfers it indoors through refrigerant pipes. The indoor unit, situated in the roof space or under the floor, disperses this warm air through the ducts to each vent. The process reverses in summer, allowing the same system to cool your home. For a detailed explanation of how a refrigerated reverse cycle system operates, please refer to our article that outlines each component.
How Is Ducted Heating Correctly Sized for Your Home?
Proper sizing is essential to ensure that a ducted heating system operates effectively during Melbourne’s chilly mornings. An undersized system struggles to warm distant rooms, while an oversized system incurs unnecessary costs. Energy.gov.au recommends selecting a model with the correct capacity for your home and consulting experts before making significant purchases like ducted heating and cooling.
During our home assessment, we evaluate the number of rooms and vents, the duct routing (whether through the ceiling or beneath the floor), whether your home is single or multi-storey, and the intended use of each room. Providing house plans can assist us in determining duct runs before our visit. For comprehensive guidance on sizing a ducted heating system tailored to your Melbourne home, refer to our sizing guide.
Is Zoning a Necessary Feature for Your New Ducted Heating System?
Zoning capability allows you to control which rooms receive heating. For instance, you might prefer to keep bedrooms unheated during the day and living areas unheated at night, rather than heating the entire house simultaneously. If your previous gas ducted heater lacked zoning, it is advisable to install a zoned system during the new installation, as it simplifies the configuration process.
Thermostat settings also play a crucial role. Energy.gov.au states that increasing heating by each degree in winter can boost your energy consumption by 5% to 10%. Most systems we install are controllable via mobile applications, enabling you to activate the heating before returning home from work, ensuring a comfortable environment upon your arrival without needing to run the system continuously throughout the day.
What Changes Are Made to Ductwork and Vents During Installation?
Every system installation includes the installation of new ducting. Existing ducting from an old gas heater often does not support a reverse cycle system and is usually filled with dust from years of operation. The new ducting is accurately sized for both heating and cooling, connecting to the same outlet points in your ceiling or floor, resulting in new vents and grilles rather than patched openings from the previous system.
For ceiling installations, we access the roof space by removing tiles or sheets, dismantling the old unit and ducts, and fitting the new system and ductwork in their place. Approximately one-third of the homes we encounter have floor ducting, where the indoor unit is installed in the subfloor, requiring careful handling due to limited access.
Where Should the Outdoor Unit Be Positioned for Optimal Performance?
A reverse cycle ducted system includes both an outdoor and an indoor unit, linked by pipes that transport refrigerant. The outdoor unit is placed outside your home. We discuss its placement with you during the in-home assessment, and if your property presents challenges, we identify the best location before installation day.
What Is the Typical Timeline for Ducted Heating Installation?
Most ducted heating installations are completed within a single day. larger homes or more complex duct layouts may extend the installation process to a second day. We confirm the expected duration during our assessment, ensuring you are well-informed about what to expect before work begins.
On installation day, our team removes the old heater, installs the new ducting and vents, sets up both the indoor and outdoor units, and connects the controller. As licensed mechanical plumbers, we can also cap the gas line of the old heater during the installation, eliminating the need for a separate tradesperson. If you continue to use gas for hot water or cooking, those connections remain intact. Before we conclude our visit, we ensure the new system operates correctly and provide instructions on using the controls.
For extensive information on what to expect on installation day, refer to our article detailing the heating and cooling installation process.
How Do the Running Costs of Ducted Reverse Cycle Heating Compare to Gas Ducted Heating?
According to Energy.gov.au, the operating costs for ducted gas heating can be significant due to high gas consumption and the electricity needed for the fans. In contrast, ducted reverse cycle systems are generally viewed as more cost-effective than gas heating. Ducted systems typically exhibit lower efficiency than wall-mounted units, mainly due to larger fans and energy loss through ductwork, making proper sizing and duct design essential.
Your running costs will vary based on your home’s size, insulation quality, zoning usage, and whether you have solar panels installed. A reverse cycle system can utilise solar power during daylight hours, a benefit that is not available with gas heating. Our comparison of ducted gas and reverse cycle heating for Melbourne homes provides a detailed analysis of running cost figures.
How Does the VEU Rebate Function When Transitioning from Gas Ducted Heating?
The Victorian Energy Upgrades (VEU) programme incentivises households that transition from gas heating to an efficient electric system. The rebate applies when an existing gas heating appliance is removed and replaced with a qualifying premium inverter reverse cycle system. Generally, homes that have never had gas heating will not be eligible for the rebate.
We manage all VEU paperwork during the installation process, and the rebate is deducted from your payment at the point of sale, eliminating the need for you to complete forms or wait for a refund. Our article on the VEU rebate clarifies the eligibility criteria and coverage details.
What Key Questions Should You Ask Before Committing to a Ducted Heating Installation Quote?
Ducted heating quotes can be complex to compare, as one quote may include elements that another omits. Use these questions to evaluate quotes effectively:
- Is the quoted price all-inclusive, with the VEU rebate already factored in?
- Does the quote include new ducting and vents, or does it suggest reusing existing ducts?
- Was the system sized based on an in-home assessment or merely through a phone consultation?
- Is zoning included, and how many zones does the quote cover?
- Who will be responsible for removing the old gas heater and capping the gas line?
- Will the installation be carried out by the installer’s own team or subcontracted?
- What workmanship guarantee accompanies the installation?
