Ducted Heating Installation: Explore Essential Options

The installation of ducted heating entails setting up a central unit that distributes either warm or cool air throughout your home via ducts installed in the ceiling or beneath the floor. Each room receives air through strategically located vents, with temperature control managed via a wall-mounted controller. This setup enables effective climate management throughout your entire home. In Melbourne, electric reverse cycle ducted heating has become a preferred option for many homeowners. This system efficiently provides warmth during winter and cooling in summer through the same vents. Gas ducted heating continues to be a viable alternative, and this guide presents a thorough comparison of both systems.

This guide 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 relevant to transitioning to electric systems, and essential questions to pose to any installer before committing to a decision.

Key Insights into Ducted Heating Installation

• The Australian Government’s energy.gov.au highlights that reverse cycle air conditioners have efficiency ratings ranging from 300% to 600%.
• Energy.gov.au also indicates that ducted reverse cycle systems operate more economically compared to gas heating systems.
• Most installations can typically be completed within a single day; however, larger homes or complex duct layouts may necessitate an additional day.
• The VEU rebate is applicable when replacing an old gas heater with a qualifying reverse cycle system.

Which Ducted Heating Solutions Are Ideal for Your Home?

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

• 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 set of vents. This is the most commonly installed system, and you can find further details on our ducted reverse cycle air conditioning page.
• Gas Ducted Heating. A gas furnace generates warm air, which a fan circulates through the ducts. Although installations of gas ducted heating continue, many Melbourne residents 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, an add-on cooling system can be integrated, utilising the same ducts and controller for cooling purposes.

If your gas heater is aging, frequently requiring repairs or leading to high operating costs, consider upgrading to an electric reverse cycle ducted system. This option provides heating and cooling in a single installation. Our comprehensive guide on replacing gas ducted heating with electric heating offers further insights into this transition.

What Mechanism Powers Reverse Cycle Ducted Heating?

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.

In winter, the outdoor unit extracts heat from the surrounding air and transports it indoors through refrigerant pipes. The indoor unit, located in the roof space or beneath the floor, distributes this warm air via 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 operates, please refer to our article outlining each component.

How Is Your Ducted Heating System Appropriately Sized?

Proper sizing is essential 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 expenses. Energy.gov.au recommends selecting a model with the appropriate 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 (either 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 comprehensive guidance on sizing a ducted heating system tailored to your Melbourne home, refer to our sizing guide.

Is Zoning a Vital 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 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 significantly impact 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 needing 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 appropriately sized for both heating and cooling, connecting to the same outlet points in your ceiling or floor, resulting in new vents and grilles instead of 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 Located?

A reverse cycle ducted system comprises both an outdoor and an indoor unit, connected through pipes that transport refrigerant. The outdoor unit is positioned 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 before the installation day.

What Is the Expected Duration for Ducted Heating Installation?

Most ducted heating installations are completed within a single day. larger homes or more intricate duct layouts may extend the installation over two days. We confirm the expected duration during our assessment, ensuring you are 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 will remain intact. Before we conclude our visit, we ensure that the new system functions correctly and provide guidance on how to use the controls.

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 regarded as more cost-effective compared to gas heating. Ducted systems tend to be less efficient 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 vary based on your home’s size, insulation quality, zoning usage, and whether you have solar panels installed. A reverse cycle system can utilise 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 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, if a home has never had gas heating, the rebate will not apply.

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 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 evaluate quotes:

• Is the quoted price comprehensive, with the VEU rebate already included?
• 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 removing the old gas heater and capping the gas line?
• Will the installation be carried out by the installer’s own team or subcontracted out?
• What workmanship guarantee accompanies the installation?
