Flued gas heaters
Flued gas heaters have a pipe (flue) to take gases outside so the air in your room stays clean. Since installation is required, there are extra costs involved and you won't be able to move your heater from room to room. You can often use an existing fireplace to place your heater and take advantage of the chimney.
- Emissions are directed outside rather than into the room
- Better for spot heating
- Can be used in small rooms
- Suitable for allergy sufferers, asthmatics and people with respiratory issues
Cons
- More expensive
- Requires installation which adds more cost
- Not as energy-efficient
- Needs gas filter installation
Unflued gas heaters
An unflued gas heater is a portable heater that can either use a gas bottle tucked into the back or can be connected to a gas point in your home. Most of the gas turns into heat. This lets it heat up a room quickly. As the gas isn't flued or filtered out of the home these are recommended for larger living areas rather than single, small room such as bedrooms or studies.
Some states in Australia have regulations over where unflued gas heaters can be placed. Check first before purchasing.
- Portable
- More energy-efficient and cheaper to run
- Heats a room faster
- Some models have safety features
Cons
- Gas emissions go back into the room, so ventilation is crucial
- Illegal to use in small and enclosed spaces
- Produces carbon monoxide and nitrous oxide
- May irritate respiratory issues or allergies
What type of gas heater is best?
The best gas heater for you is one that suits your home and your needs. Here are a few key features to consider before choosing your gas heater:
Room size
The heater you buy should adequately heat the room size it's in. As a guide, 1kWh can heat around 10 square metres (sqm).
Be aware that it's illegal to use unflued heaters in smaller rooms. Check your state's regulations before shopping.
Gas type
Gas heaters run on either LPG or natural gas. Choose the option that your home is installed with.
Price
Unflued heaters tend to cost from $400-$1,500. Flued heaters are more expensive ranging from $1,200-$2,200. The price will depend on size, quality and extra features.
Gas consumption
The higher the MJ/h (megajoule) rating the more gas will be used for faster heating. Flued heaters have input of up to 30MJ. Unflued heaters have a maximum input of 25MJ.
Safety features
Common safety features include a child safety lock and tilt switch which shuts the unit down if it's tipped over. These are particularly handy if you have young children or pets.
Extra features
Popular features you may enjoy for convenience include a remote control, thermostat, timer, electronic ignition and filter-clean warning.
Gas vs electric heaters
Deciding on whether a gas or an electric heater is the right choice for your home? These are the main differences between the two.
Gas heaters
- More expensive than electric heaters
- Cheaper to run than electric heaters though it requires more gas for the same amount of heat
- Suitable for large rooms, but need to have good airflow if buying an unflued model due to emissions
- Work at any time gas is available, so you can still keep warm during power cuts
- Produce less carbon dioxide than electric heaters
- Often requires professional installation
Electric heaters
- Cost less than gas heaters in general, but electricity costs more for ongoing costs than gas
- Usually smaller and more portable
- Suitable for smaller rooms or if you have children around
- More sustainable if you use solar power

Gas heater safety and regulations
- Before purchasing, be sure to check out the gas safety regulations for your state for information around ventilation for gas appliances.
- Victoria has banned the sale of some gas heaters, and unflued heaters must use liquid petroleum gas (LPG).

- Check that the heater you want to purchase has been certified for use by the Australian Gas Association.
- To ensure proper airflow, clean filters (if applicable) regularly.
- Ensure kids, pets and any flammable objects stay at least 1 metre away from gas heaters.
- Do not leave a gas heater on overnight or in a room that you sleep in.
- When choosing a flued gas heater, ask a certified gas fitter to complete the installation.
- As well as having a smoke alarm, consider installing a carbon monoxide alarm for any type of gas heater you purchase.
Frequently asked questions
How long do gas heaters last?
The average lifespan of a gas heater is around 10-15 years. Of course, this will depend on the quality and maintenance of the appliance. Keeping up with annual servicing and following regular maintenance tips can help you get more out of your gas heater and ensure it works efficiently for longer.
What type of heater is the cheapest to run?
Unfortunately, there is no one-size-fits-all answer when it comes to which type of heater is the least expensive to run. Generally speaking, gas heaters are cheaper than electric models for heating large spaces. However, the actual cost depends on a number of factors, such as the price of electricity and gas in your area and the size of your space.
Are gas heaters safe for the bedroom?
Yes, gas heaters can be safely used in the bedroom if installed and maintained correctly. It is important to ensure that your heater has the appropriate safety features, such as a flame failure device and an oxygen depletion sensor.
Can I get carbon monoxide poisoning from a gas heater?
A faulty and poorly installed gas heater can possibly cause carbon monoxide poisoning. You can use CO detectors and ensure your gas heater is working properly to avoid carbon monoxide poisoning.
Can I leave my gas heater on overnight?
While modern gas heaters offer a ton of safety features, you still shouldn't leave your gas heater on when you go to bed.
Do I need to open a window when using a gas heater?
If your room isn't well-ventilated or doesn't have air vents, it is best to keep a door or window open to allow better airflow.
What's the most efficient gas heater?
We've found that convection gas heaters are the cheapest to run. On average, they'll set you back $248 during the Australian winter.
Are newer gas heaters more efficient?
They can be. As technology advances gas heaters become more economic. The Omega Altise Briganger, Rinnai Avenger 25 and Rinnai Granada 252 mentioned on our list all boast energy ratings of 5.8 stars or higher.
That said, there is always going to be a variety of heaters on the market and you'll find some that are more efficient than others.
Do gas heaters use a lot of gas?
Most gas heaters can consume 13 to 30 megajoules per hour. The amount of gas used depends on how large your room is and how strong your heat setting is. Generally the larger the room the more gas is required to heat it up. If you're using a small 45kg LPG tank a 30MJ gas heater can run for 3 hours per day for 24 days.
