Ducted Heating Installation: Key Options to Consider

Installing ducted heating involves setting up a centralised unit that distributes warm or cool air throughout your home using ducts installed in the ceiling or beneath the floor. Each room receives air through strategically positioned vents, and you can manage the temperature using a wall-mounted controller, enabling comprehensive climate control across the house. In Melbourne, many homeowners prefer electric reverse cycle ducted heating, a system that efficiently provides warmth in winter and cooling in summer through the same ventilation. Gas ducted heating remains a viable alternative, and this guide presents a thorough comparison of both systems.

This guide extensively covers the ducted heating installation process, detailing critical components such as system sizing, zoning, ductwork, the outdoor unit, and what to expect on the day of installation. We will also examine the operating costs linked to gas systems, the Victorian Energy Upgrades (VEU) rebate associated with switching to electric systems, and important questions to discuss with any installer before making your decision.

Essential Insights on Ducted Heating Installation

• According to the Australian Government’s energy.gov.au, reverse cycle air conditioners boast efficiency ratings ranging from 300% to 600%.
• Energy.gov.au further highlights that ducted reverse cycle systems operate more economically than gas heating systems.
• Typically, most installations can be completed in a single day, although larger homes or complex duct layouts may require a second day.
• The VEU rebate is applicable when replacing an old gas heater with a qualifying reverse cycle system.

What Types of Ducted Heating Solutions Are Ideal for Your Home?

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

• <a href="https://writebuff.com/air-conditioner-summer-ready-6-signs-you-must-check/">Electric Reverse Cycle Ducted Heating and Cooling.</a> This system includes both an outdoor and indoor unit, working together to heat or cool your entire home through a single set of vents. It is the most commonly installed system, with more information available on our ducted reverse cycle air conditioning page.
• Gas Ducted Heating. This system uses a gas furnace to generate warm air, which is then circulated through the ducts by a fan. While installations of gas ducted heating still occur, an increasing number of Melbourne homeowners are opting to move away from gas instead of installing 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 for cooling purposes.

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

How Does Reverse Cycle Ducted Heating Work?

Reverse cycle ducted heating operates by transferring heat instead of generating it. The Australian Government’s energy.gov.au heating and cooling guide explains that 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 directly into one unit of heat.

During winter, the outdoor unit extracts heat from the ambient air and moves it indoors via refrigerant pipes. The indoor unit, located in the roof space or under the floor, distributes 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 breakdown of how a refrigerated reverse cycle system operates, please consult our article that outlines each component.

How Is Ducted Heating Properly Sized for Your Home?

Proper sizing is crucial to ensure that a ducted heating system functions effectively during the cold mornings typical of Melbourne. An undersized system struggles to warm distant rooms, whereas an oversized system leads to unnecessary costs. 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 systems.

During our home assessment, we consider the number of rooms and vents, the duct routing (whether through the ceiling or below the floor), whether your home is single or multi-storey, and the intended use of each space. Providing house plans can help us determine 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 Beneficial Feature for Your New Ducted Heating System?

Zoning functionality allows you to control which rooms receive heating. For example, you may prefer to keep bedrooms unheated during the day and living spaces unheated at night, rather than heating the entire house continuously. 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 an important role in energy efficiency. Energy.gov.au notes that increasing heating by just one degree in winter can raise your energy consumption by 5% to 10%. Most systems we install are controllable via mobile applications, which allows 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 Changes Are Made to Ductwork and Vents During Installation?

New ducting is installed with every system installation. Existing ducting from an old gas heater often cannot accommodate a reverse cycle system and is usually filled with dust and debris 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.

Where Should the Outdoor Unit Be Positioned?

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

What Is the Typical Duration for Ducted Heating Installation?

Most ducted heating installations are typically 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 anticipate 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, negating the need for a separate tradesperson. If you continue to use 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.

For extensive information on what to expect on installation day, consult our article detailing the heating and cooling installation process.

How Do the Operating 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 required to power the fans. In contrast, ducted reverse cycle systems are generally considered more cost-effective than gas heating. Ducted systems are typically less efficient than wall-mounted units, primarily because of larger fans and energy loss through ductwork, making proper sizing and duct design essential.

Your operating 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 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 Work 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, so you do not need to fill out forms or wait for a refund. Our article on the VEU rebate clarifies the eligibility criteria and coverage details.

What Essential 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 comprehensive, with the VEU rebate already included?
• 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 just through a phone consultation?
• Is zoning included, and how many zones does the quote cover?
• Who will handle the removal of 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?
