Ducted Heating Installation: Explore Essential Options

Installing ducted heating requires the establishment of a central unit that distributes either warm or cool air throughout your home via ducts located in the ceiling or underneath the floor. Each room receives air through strategically placed vents, while temperature control is managed via a wall-mounted controller, allowing for comprehensive climate management across your entire residence. In Melbourne, electric reverse cycle ducted heating has become a popular choice among homeowners. This system effectively provides warmth during the winter months and cooling in the summer through the same vents. While gas ducted heating remains a viable option, this guide offers a thorough comparison of both systems to assist in your decision-making process.

This guide meticulously details the installation process for ducted heating, addressing essential components such as sizing, zoning, ductwork, the outdoor unit, and what to expect on the day of installation. We will explore the operating costs associated with gas systems, the Victorian Energy Upgrades (VEU) rebate linked to the transition to electric systems, and key questions to pose to any installer before making your final choice.

Essential Insights into Ducted Heating Installation

• The Australian Government’s energy.gov.au reports that reverse cycle air conditioners can achieve efficiency ratings between 300% and 600%.
• Energy.gov.au also indicates that ducted reverse cycle systems tend to operate more economically than gas heating systems.
• Most installations can generally be completed within a single day; however, larger properties or complex duct layouts may necessitate an additional day.
• The VEU rebate applies when replacing an old gas heater with a qualifying reverse cycle system.

Which Ducted Heating Solutions Are Best for Your Home?

In Melbourne, homeowners have two primary types of ducted heating systems to choose from, with an additional option to integrate cooling into an existing gas system.

• Electric Reverse Cycle Ducted Heating and Cooling. This system comprises both an outdoor and an indoor unit that work in tandem to heat or cool your entire home through a single set of vents. This is the most widely installed system, with further details 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 installations of gas ducted heating continue, many Melbourne homeowners are choosing to transition away from gas rather than installing new gas heaters.
• Add-on Cooling for an Existing Gas Heater. If your gas ducted heater is relatively modern, an add-on cooling system can be integrated, utilising the same ducts and controller for cooling purposes.

If your gas heater is ageing and frequently requires repairs, or if it leads to high operating costs, consider upgrading to an electric reverse cycle ducted system. This option offers both heating and cooling in a single installation. For more information on transitioning from gas ducted heating to electric heating, consult our comprehensive guide.

What Is the Mechanism Behind Reverse Cycle Ducted Heating?

Reverse cycle ducted heating operates 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 ambient air and transports it indoors via refrigerant pipes. The indoor unit, situated in the roof space or beneath the floor, distributes this warm air through the ducts to each vent. The process reverses in summer, enabling the same system to cool your home. For a detailed explanation of how a refrigerated reverse cycle system functions, please refer to our article outlining each component.

How Is Your Ducted Heating System Accurately Sized?

Proper sizing is essential to ensure that a ducted heating system operates efficiently during the chilly Melbourne 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 significant purchases such as ducted heating and cooling.

During our home assessment, we consider 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 an Important Feature for Your New Ducted Heating System?

Zoning functionality allows you to control which rooms receive heating. For instance, you may prefer to keep bedrooms unheated during the day while leaving living areas unheated at night, rather than heating the entire house simultaneously. If your previous gas ducted heater did not include zoning, it is advisable to install a zoned system during the new installation, as it simplifies the configuration process.

Thermostat settings also significantly influence energy consumption. Energy.gov.au states that increasing heating by each degree in winter can raise your energy consumption by 5% to 10%. Many systems we install can be controlled via mobile applications, allowing you to activate the heating before returning home from work, ensuring a warm environment upon your arrival without the need for continuous operation throughout the day.

What Modifications 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 suit a reverse cycle system and is usually filled with dust from years of use. The new ducting is properly 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 feature floor ducting, where the indoor unit is installed in the subfloor, requiring careful handling due to limited access.

What Is the Best Position for the Outdoor Unit?

A reverse cycle ducted system consists of both an outdoor and an indoor unit, connected via pipes that transport refrigerant. The outdoor unit is situated outside the house. We discuss its placement with you during the in-home assessment, and if your property presents challenges, we identify the most suitable location prior to the installation day.

What Is the Typical Timeline for Ducted Heating Installation?

Most ducted heating installations are completed in a single day. larger homes or more intricate 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 anticipate before work commences.

On the day of installation, 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 utilise gas for hot water or cooking, those connections remain intact. Before concluding our visit, we ensure that the new system operates correctly and provide instructions on how to use the controls.

How Do 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 considered to be more cost-effective than gas heating. Ducted systems typically exhibit lower efficiency than wall-mounted units, primarily due to larger fans and energy losses through ductwork, making proper sizing and duct design vital.

Your running costs will fluctuate based on your home’s size, the quality of insulation, zoning usage, and whether you have solar panels installed. A reverse cycle system can leverage your solar power during daylight hours, a benefit that is unavailable with gas heating. Our comparison of ducted gas and reverse cycle heating for Melbourne homes provides an in-depth 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 shift 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, if a home has never had gas heating, the rebate will not apply.

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 fill out forms or wait for a refund. Our article on the VEU rebate clarifies the eligibility criteria and coverage details.

What Key Factors Should You Consider Before Accepting a Ducted Heating Installation Quote?

Ducted heating quotes can be intricate to compare, as one quote may include elements that another omits. Use these questions to effectively assess quotes:

• Is the quoted price all-inclusive, with the VEU rebate already taken into account?
• Does the quote encompass 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 accommodate?
• Who will be responsible for the removal of the old gas heater and capping the gas line?
• Will the installation be performed by the installer’s own team or subcontracted out?
• What workmanship guarantee accompanies the installation?
