Ducted Heating Installation: Explore Essential Options

The installation of ducted heating includes setting up a central unit that efficiently distributes either warm or cool air throughout your home via ducts located in the ceiling or beneath the floor. Each room receives air through carefully positioned vents, and temperature control is managed via a wall-mounted controller. This enables seamless climate regulation for your entire home. In Melbourne, electric reverse cycle ducted heating is a popular option among homeowners, providing effective heating in winter and cooling in summer through the same vents. Gas ducted heating remains a feasible alternative, and this guide offers a comprehensive comparison of both systems.

This guide thoroughly details the installation process for ducted heating, addressing vital components such as sizing, zoning, ductwork, the outdoor unit, and what to expect on the day of installation. We will explore the operating costs linked to gas systems, the Victorian Energy Upgrades (VEU) rebate relevant to the shift towards electric systems, and essential questions to pose to any installer prior to making a choice.

Key Insights into Ducted Heating Installation

• The Australian Government’s energy.gov.au reports that reverse cycle air conditioners exhibit efficiency ratings ranging from 300% to 600%.
• Energy.gov.au also notes that ducted reverse cycle systems tend to operate more economically than gas heating systems.
• Most installations can generally be completed in a single day; however, larger homes 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 Best Suit Your Home?

Homeowners in Melbourne can choose from two primary types of ducted heating systems, with an additional option to incorporate cooling into an existing gas system.

• Electric Reverse Cycle Ducted Heating and Cooling. This system comprises both an outdoor and an indoor unit, working in tandem to heat or cool your entire home through a single set of vents. It is the most frequently installed system, with more information available on our ducted reverse cycle air conditioning page.
• Gas Ducted Heating. A gas furnace generates warm air, circulated through the ducts by a fan. While gas ducted heating installations are still undertaken, 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, an add-on cooling system can be integrated, utilising the same ducts and controller for cooling purposes.

If your gas heater is ageing, frequently requiring repairs or resulting in high operational costs, consider upgrading to an electric reverse cycle ducted system. This option provides both heating and cooling in one installation. Our detailed guide on replacing gas ducted heating with electric heating offers further insights into this transition.

How Does Reverse Cycle Ducted Heating Operate?

Reverse cycle ducted heating functions by transferring heat rather than generating it. As stated in 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 transports it indoors through refrigerant pipes. The indoor unit, located in the roof space or under the floor, circulates this warm air via 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 outlining each component.

How Is Your Ducted Heating System Properly Sized for Maximum Efficiency?

Correct sizing is essential to ensure that a ducted heating system operates effectively during the chilly Melbourne mornings. An undersized system struggles to warm distant rooms, while an oversized system incurs unnecessary expenses. Energy.gov.au advises 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 (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 Vital Feature for Your New Ducted Heating System?

Zoning functionality enables you to control which rooms receive heating. For example, 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 significantly influence energy consumption. Energy.gov.au indicates that increasing heating by each degree in winter can raise your energy consumption by 5% to 10%. Many systems we install are controllable 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 correctly 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.

What Is the Ideal Position for the Outdoor Unit?

A reverse cycle ducted system comprises both an outdoor and an indoor unit, linked through 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.

How Long Does Ducted Heating Installation Typically Take?

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 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 we conclude our visit, we ensure that the new system functions 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 significant due to high gas consumption and the electricity needed for the fans. Conversely, ducted reverse cycle systems are generally viewed 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 Incentivise the Transition from Gas Ducted Heating?

The Victorian Energy Upgrades (VEU) programme incentivises households that switch 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, with the rebate 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 Critical Factors Should You Consider Before Accepting a Ducted Heating Installation Quote?

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

• Is the quoted price comprehensive, incorporating the VEU rebate?
• Does the quote include new ducting and vents, or does it propose 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 executed by the installer’s own team or subcontracted out?
• What workmanship guarantee accompanies the installation?
