Ducted Heating Installation Options to Explore

The installation of ducted heating involves setting up a central unit that effectively distributes either warm or cool air throughout your home via ducts located in the ceiling or beneath the floor. Each room benefits from airflow through strategically placed vents, while a wall-mounted controller manages temperature settings, allowing for holistic climate control across your entire residence. In Melbourne, many homeowners favour electric reverse cycle ducted heating, which efficiently provides warmth in winter and cooling in summer through the same vents. Alternatively, gas ducted heating remains an option, and this guide delivers a detailed comparison of both systems.

This guide presents a thorough overview of the ducted heating installation process, covering essential aspects such as system sizing, zoning, ductwork, the outdoor unit, and what to expect on installation day. We will also analyse the operating costs associated with gas systems, the Victorian Energy Upgrades (VEU) rebate for transitioning to electric systems, and key questions to ask any installer before making a commitment.

Key Information on Ducted Heating Installation

• The Australian Government’s energy.gov.au indicates that reverse cycle air conditioners have efficiency ratings between 300% and 600%.
• Energy.gov.au also notes that ducted reverse cycle systems typically operate more economically than gas heating systems.
• Most installations can usually be completed in a single day; however, larger homes or more intricate duct layouts may require an additional day.
• The VEU rebate is applicable when replacing an old gas heater with a qualifying reverse cycle system.

What Are the Best Ducted Heating Solutions for Your Home?

In Melbourne, homeowners can choose between two primary types of ducted heating systems, which can also include cooling options for existing gas systems.

• Electric Reverse Cycle Ducted Heating and Cooling. This system features 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 widely installed system, with further information available on our ducted reverse cycle air conditioning page.
• <a href="https://limitsofstrategy.com/ducted-heating-system-sizing-for-homes-in-melbourne/">Gas Ducted Heating.</a> A gas furnace produces warm air, which is circulated through the ducts via a fan. While gas ducted heating remains a viable option, many homeowners in Melbourne are opting for alternatives rather than installing new gas heaters.
• Add-on Cooling for an Existing Gas Heater. If your gas ducted heater is relatively modern, you can incorporate an add-on cooling system that utilises the same ducts and controller for cooling purposes.

If your gas heater is outdated, frequently requires repairs, or incurs high running costs, consider upgrading to an electric reverse cycle ducted system. This solution provides both heating and cooling in a single installation. For more details on transitioning from gas ducted heating to electric heating, consult our in-depth guide.

How Does Reverse Cycle Ducted Heating Work?

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 that in heating or cooling energy, achieving efficiency ratings between 300% and 600%. This contrasts with electric bar heaters, which convert one unit of electricity into one unit of heat.

In winter, the outdoor unit extracts heat from the ambient air and transports it indoors through refrigerant pipes. The indoor unit, situated in the roof space or beneath the floor, distributes this warm air via the ducts to each vent. This process reverses in summer, allowing the same system to cool your home. For an in-depth explanation of how a refrigerated reverse cycle system operates, please refer to our article that details each component.

How Is Your Ducted Heating System Properly Sized?

Proper sizing is vital to ensure that a ducted heating system operates efficiently 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 appropriate capacity for your home and consulting experts before making major purchases like ducted heating and cooling.

During our home assessment, we assess 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 prior to our visit. For detailed guidance on sizing a ducted heating system tailored to your Melbourne home, refer to our sizing guide.

Is Zoning a Necessary Feature for Your Ducted Heating System?

Zoning capability enables 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 at once. 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 are also significant. Energy.gov.au states that increasing heating by each degree in winter can raise your energy consumption by 5% to 10%. Most systems we install can be controlled via mobile applications, allowing you to activate the heating before returning home from work, ensuring a comfortable environment upon your arrival without the need to run the system continuously throughout the day.

What Modifications Are Made to Ductwork and Vents During Installation?

New ducting is installed with each system installation. Existing ducting from an old gas heater often does not support a reverse cycle system and is typically filled with dust from years of use. 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 consists of both an outdoor and an indoor unit, linked by pipes that transport refrigerant. The outdoor unit is installed outside your home. We discuss its placement with you during the in-home assessment, and if your property presents any challenges, we identify the most suitable location before installation day.

What Is the Typical Duration 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 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, removing 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 substantial due to high gas consumption and the electricity required for the fans. In contrast, ducted reverse cycle systems are generally regarded as more cost-effective than gas heating. Ducted systems typically exhibit lower efficiency than wall-mounted units, primarily due to larger fans and energy loss through ductwork, making proper sizing and duct design essential.

Your running costs will fluctuate 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 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. Homes that have never had gas heating generally do not qualify for the rebate.

We handle 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 Finalising 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 accounted for?
• Does the quote include new ducting and vents, or 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 performed by the installer’s own team or subcontracted?
• What workmanship guarantee accompanies the installation?
