Which Heating System Fits Your Home?
Reverse cycle can heat and cool using one system, while gas and electric resistance have different installation, safety and ongoing-cost considerations. Start with the rooms you use, your local climate and whether you also need cooling. Compare complete quotes and household running-cost assumptions, then check the proposed model, capacity, controls and service support.

Compare the Main Heating Options
Start with the rooms you need to heat and whether you also want cooling. These systems have different installation and operating requirements; a quoted price is only useful alongside its scope.
| System | What it does | What to check |
|---|---|---|
| Reverse-cycle split system | Heats and cools a room or open area by moving heat. | Placement, model capacity and local climate performance. |
| Ducted reverse cycle | Distributes heated or cooled air through ducts. | Duct design, covered rooms, zones and controls. |
| Gas heating | Burns gas to provide heat, through a room heater or ducted system. | Gas supply, ventilation, safety and servicing. |
| Electric resistance | Uses an element to generate heat, such as a panel or oil-column heater. | Intended use, electricity consumption and safe placement. |
The Australian Government heating overview also covers wood and hydronic heating. Those involve additional questions about fuel, emissions, equipment and the property; this guide focuses on reverse cycle, gas and electric resistance.
Reverse Cycle: Heating and Cooling in One System
A reverse-cycle air conditioner moves heat into the home when heating and out when cooling. It can provide more heat than the electrical energy it consumes, unlike a conventional resistance heater. See Energy Rating: heating and cooling.
A wall split, multi-split and ducted installation cover space differently. Discuss which rooms need conditioning at the same time, how air will reach them and where equipment can fit. For layout considerations, see our Split System vs Ducted guide.
Compare the proposed model's heating capacity, local-climate efficiency and noise information. A headline efficiency figure is not a fixed bill saving or a guarantee of comfort in every home.
Gas Heating: Include Safety and Ongoing Costs
Gas room heaters and ducted systems differ in how they supply heat and manage combustion gases. Ask a licensed gasfitter whether the proposed appliance, ventilation and installation are suitable and permitted at your property. Having gas connected does not establish that another gas heater is your lowest-cost option.
Energy Safe Victoria gas-heater guidance explains carbon monoxide risks and the need for qualified servicing. Follow the manufacturer and your local regulator's requirements, and keep required ventilation clear. Avoid sealing vents to improve comfort without a qualified assessment.
When comparing a change from gas to electric, include the gas usage, any electricity used by fans and gas charges that would remain.
Electric Resistance: Match the Heater to Its Use
Panel, fan and oil-column heaters use electricity to generate heat directly. The Australian Government overview explains these types and their different heat-delivery methods.
Compare the purchase cost with how often the heater will run and the space it needs to warm. Occasional use in one room and regular whole-home heating are different requirements; a cheap purchase does not establish a cheap winter bill.
Follow the product's placement and operating instructions, including clearance from combustible materials. Ask for advice if you are unsure about the appliance or electrical supply. This guide does not prescribe power-board, wiring or repair arrangements.
Choose Capacity for Your Home and Local Climate
Cold weather does not automatically make gas the best choice. Ask for a reverse-cycle model whose heating performance suits local conditions, and have the supplier explain its operating range and capacity at relevant outdoor temperatures.
The Victorian reverse-cycle buyers guide recommends an onsite load assessment. Room area alone is insufficient: construction, insulation, glazing, ceiling height, orientation and occupied rooms affect demand. Heating and cooling capacities may also differ.
Ask the supplier to explain their sizing calculation. Avoid a fixed extra percentage for a city or an instruction to oversize the unit as a substitute for assessing the property.
Compare Complete Quotes and Running-Cost Assumptions
Give each supplier the same brief: rooms, usage pattern, current system, access and whether cooling is needed. Then compare:
- Equipment: exact models, indoor/outdoor units, capacity and controls.
- Installation: ducts, electrical or gas work, old-system removal and exclusions.
- Ongoing costs: estimated energy use, tariff assumptions, care and service support.
- Payment: confirmed incentives and the final amount payable.
The Australian Energy Regulator tariff guide explains single-rate, time-of-use, controlled-load and demand charging. Ask which terms apply to the proposed system and your account; label energy-use estimates are not your household bill.
The regulator also explains usage and daily supply charges. If gas stays connected for cooking or hot water, its supply charge remains part of the household budget. Ask the retailer which charges would stop, and about disconnection costs, if you remove the connection entirely.
Compare Models, Warranty and Local Support
Choose using the actual model and written terms rather than a brand-wide best-value label. Ask about heating performance, noise, controls, parts and local service availability.
Read equipment and installation warranties separately. Check parts, labour, call-out costs and maintenance conditions. A stated warranty period is not a promise that every unit will last a particular number of years.
The ACCC warranty guidance explains that warranties are additional to consumer guarantees. Keep the quote, model details, invoice and handover documents so the terms can be checked if a problem arises.
Check Eligible Heating and Cooling Incentives
Programme information was checked on 14 October 2026. Confirm the property, product, provider and application requirements before committing to an installation.
| Location | Starting point | Your next check |
|---|---|---|
| Victoria | VEU heating and cooling discounts | An approved reverse-cycle product and an accredited provider or their partner installer. Offers depend on the upgrade. |
| NSW | Air conditioner upgrade incentive | Eligible new or replacement systems, provider terms and the nomination form before installation. |
| South Australia | REPS energy-saving activities | Which heating/cooling activity and offer a participating provider currently supplies. |
| ACT | Home Energy Support | Concession-card, owner-occupation, property and programme conditions; get programme pre-approval before accepting a quote. |
NSW also has a larger postcode-based air-conditioning offer, subject to location, provider, funding and programme terms. Use the national rebates and assistance finder for other locations and offers.
Have each incentive named in the quote, with its amount and the remaining payment. An upfront discount, a later rebate and a repayable loan are different. Application timing varies by programme; arrange eligibility checks early rather than relying on a generic rebate figure.
Agree the Installation and Handover Scope
Ask for a site assessment and a written schedule covering access, disruption and any connection work. Ducts, outdoor-unit placement and the electrical supply should be assessed for the proposed equipment rather than assumed reusable.
For regulated refrigerant work, check the technician's current licence and its scope using the ARC licence check. Relevant electrical, gas and other trade requirements also apply to their part of the job. Check licences and insurance before hiring; The Wombat checks ABNs.
Agree who completes each part of the installation, removal and commissioning. At handover, request the operating instructions, required compliance documents and equipment/installation warranty. Installation time depends on the job; this guide does not promise a standard number of hours or days.
Get Faults Assessed Safely
If heating is weak, bills change or a fault code appears, record what you notice and consult the model's instructions or service provider. Do not open equipment or attempt gas, electrical or refrigerant repairs from a general guide.
Carbon monoxide cannot be seen or smelled. Gas heaters can produce dangerous carbon monoxide. If you suspect exposure, move everyone to fresh air immediately and seek urgent medical assistance. Call 000 for an emergency. See HealthyWA carbon monoxide safety for the warning signs and emergency guidance.
A heater that appears to run is not proof that it is safe. Have a qualified technician assess faults and safety concerns before relying on the equipment.
Follow the Model and Local Servicing Requirements
Ask the installer which owner-care tasks are appropriate and when professional servicing is needed. Follow the model manual and relevant local guidance rather than a universal maintenance timetable or annual budget.
For gas heating, use a qualified gasfitter for servicing and combustion-safety checks; see Energy Safe Victoria and your own jurisdiction's regulator. For air conditioning, arrange appropriate licensed work and follow the manufacturer's filter-care instructions.
Keep service records and ask about parts, labour and call-out costs. This guide does not predict a standard service life, failure age or repair bill.
Read Energy Labels for the System You Are Comparing
For labelled air conditioners, compare similar-size models with similar features in your local climate zone. The Energy Rating label guide separates heating and cooling ratings, capacity, estimated energy use and noise information.
Some systems, including ducted and multi-split air conditioners, are not required to display the Zoned Energy Rating Label. Ask for the relevant performance data if no label is shown; absence alone does not establish non-compliance.
Heating capacity describes delivered heat, while electrical input describes power consumed. A rating or COP measured under stated test conditions is not a constant household saving. Ask the supplier to connect product data with the rooms, climate and usage pattern in your brief.
