Reverse Cycle Air Conditioner – The Best All-In-One Heating & Cooling Solution
What Is Reverse Cycle Air Conditioner?
If you’re looking for a heater that doubles as an air conditioner, a reverse cycle air conditioner is the best choice. These systems heat your home in winter and cool it in summer, making them a cost-effective and energy-efficient solution for year-round comfort.
How It Works
Reverse cycle air conditioners work by transferring heat rather than generating it, making them highly energy-efficient.
In winter, they extract heat from the outside air and pump it indoors to warm your space.
In summer, the process is reversed: they remove heat from inside your home and release it outside, keeping your rooms cool and comfortable.
Types of Reverse Cycle Systems
- Split System Air Conditioners – Split systems are a popular and energy-efficient choice for heating and cooling single rooms or small spaces. They consist of an indoor unit mounted on a wall and an outdoor compressor that regulates temperature by absorbing or releasing heat. These systems are easy to install, quiet, and cost-effective.

- Ducted Reverse Cycle Systems – Designed for whole-home climate control, these systems use a network of ducts to distribute heated or cooled air to multiple rooms.
- Multi-Split Systems – A flexible option for homes with multiple rooms, multi-split systems connect several indoor units to one outdoor unit. This allows for zoned heating and cooling, making it ideal for households that want independent temperature control in different areas.
Why Choose a Reverse Cycle AC?
- Year-Round Comfort – These systems provide both heating in winter and cooling in summer, making them a versatile, all-in-one solution for any home.
- Energy Efficiency – Reverse cycle air conditioners are among the most energy-efficient heating options, especially in milder climates. For every 1kW of electricity used, they can produce 3–5kW of heat, giving them a 300–500% efficiency rate. In comparison, traditional electric and gas heaters typically only output 1kW of heat per 1kW of energy used.
- Long-Term Cost Savings – While the initial cost of a reverse cycle system may be higher than other heaters, it pays off in the long run with lower electricity bills and a lifespan of 10–15 years.
- Eco-Friendly – Produces fewer greenhouse gas emissions compared to gas or electric heaters.
Cons of a Reverse Cycle Air Conditioning
- Higher Upfront Cost – The initial purchase and installation cost is higher compared to basic electric or gas heaters.
- Requires Professional Installation – Unlike portable heaters, reverse cycle systems must be installed by a licensed technician like Radi Air.
- Outdoor Unit Space Needed – Requires an external compressor unit, which may not be suitable for apartments or homes with limited outdoor space.
Electric Heaters – Budget-Friendly & Portable Heating
What is an Electric heater?
Electric heaters are one of the most common and affordable heating options. You’ll often find them at retailers like Kmart and Big W. These plug-in heaters are ideal for small rooms, occasional use, or for renters who need a portable solution without permanent installation.
How it works?
There are several types of electric heaters, each working in slightly different ways:
- Convection heaters – Warm the air in a room and circulate it for even heat distribution, making them ideal for bedrooms and living spaces. They use electricity to heat internal elements, with some models featuring fans for faster warmth.
- Radiant Heaters – Provide direct heat to people and objects, rather than the air. Some models come with built-in fans for faster heat distribution.
- Fan Heaters – Known for their compact size and quick heat, but they can be noisy. Ideal for short-term or spot heating.
- Oil Column Heaters – Take longer to heat up but retain warmth long after being turned off, making them more energy-efficient over longer periods.
- Ceramic heaters – Uses ceramic plates to generate and distribute heat efficiently. Compact and fast-heating, they’re great for small to medium rooms. Many models feature adjustable settings, oscillation, and safety features like tip-over protection. While energy-efficient for targeted heating, they’re best for short-term or supplemental warmth rather than whole-home heating.
Why choose electrical heater?
1. Affordable Heating Option
Electric heaters are generally cheaper to buy upfront compared to gas or reverse cycle AC. You’ll find options starting as low as $30, making them ideal for budget-conscious buyers or renters.
2. Plug-and-Play Convenience
No installation required, just plug them into a power outlet and you’re good to go. This makes them perfect for quick, portable heating in any room.
3. Versatility for Any Space
From compact fan heaters for bathrooms to oil column heaters for bedrooms, electric heaters come in all sizes to suit different needs.
Cons of Electric Heaters
1. Higher Running Costs
Electricity is often more expensive than gas, so running electric heaters for long periods, especially in larger spaces can quickly add up on your power bill.
2. Limited Heating Range
Most electric heaters are best suited for small to medium-sized rooms. They struggle to efficiently heat large open-plan areas or entire homes.
3. Can Be Noisy
Fan-based models can be quite loud, which may be distracting in quiet environments like bedrooms or home offices.
4. Slower to Warm Up
Oil column and convection heaters take longer to heat a room compared to gas or reverse cycle systems, which deliver faster warmth.
5. Not Ideal for Long-Term, Whole-Home Use
Electric heaters are better for short-term or zone heating. For long-term, whole-home comfort, reverse cycle air conditioning is usually more cost-effective and efficient.
Gas Heaters – Powerful Heating for Larger Spaces
What Is a Gas Heater?
Gas heaters are a strong option for larger homes or colder climates, offering fast, effective heating. Some models are styled as gas fireplace heaters, adding a warm, ambient touch to your living space.
How it works?
Gas heaters burn natural gas or LPG to generate heat. They may require proper ventilation to safely remove emissions. Here are the main types:
- Portable Gas Heaters – Easy to move from room to room, offering flexible heating for larger spaces. However, they must be used in well-ventilated areas due to the release of emissions, making proper airflow essential for safety. Popular brands like Rinnai are known for reliable performance, safety features, and ease of use. Many models come with thermostats, timers, and flame-failure devices for added convenience and protection. These heaters are great for renters or those needing temporary, powerful warmth, but they do require access to gas bottles and regular maintenance.
- Flued Gas Heaters – These units vent emissions outside, making them safer and cleaner for indoor use. They are fixed in place and are ideal for consistent heating in one area.
- Gas Ducted Heating – A centralised system that distributes heat through ducts to multiple rooms. Perfect for whole-home heating, especially in colder regions.
Why Choose a Gas Heater?
1. Faster Heating
Gas heaters provide immediate warmth, unlike electric or reverse cycle systems, which may take time to warm up. This makes gas heaters ideal for quickly heating a room during cold weather.
2. Lower Running Costs
Gas is typically cheaper than electricity, meaning gas heaters can be more economical to run, especially in larger spaces or for long periods.
3. Ideal for Larger Spaces
Gas heaters are highly effective at heating large areas, such as open-plan living spaces, where electric heaters may struggle or be inefficient.
4. Less Dry Air
Unlike electric heaters, which can dry out the air, gas heaters tend to maintain humidity levels, making them a more comfortable choice for extended use.
Cons of Gas Heater
- Safety Risks
While modern gas heaters are designed with safety features, poor maintenance or incorrect use can lead to gas leaks, fire hazards, or carbon monoxide exposure, especially in older units. Regular servicing and proper ventilation are key to staying safe.
- Fluctuating Running Costs
Gas is generally cheaper than electricity, but prices can vary based on your local provider and seasonal demand. Running costs also depend on the efficiency of the unit and how often it’s used.
- Not Ideal for Small or Sealed Spaces
Gas heaters are not recommended for bedrooms or small, enclosed areas due to ventilation and safety requirements. Many models are restricted by law from being used in sleeping areas.
- Requires Ongoing Maintenance
To stay safe and efficient, gas heaters need regular servicing, ideally once a year. This adds to long-term costs and upkeep.
