Portable gas heaters are unflued models needing only a gas bayonet outlet and (usually) a power point to plug into, but need an open window or door so as to vent the noxious gases.
Flued gas heaters require a flue kit and space to put the kit so they can vent noxious gases outdoors. Each deliver quick, efficient warmth, and lots of it – but they're not right for everyone. See our buying guide for advice on whether this type of heater is a good option for you, and find out how we test gas heaters.
If you are heating a small space, you might be better off looking at our electric heater reviews.

We recommend gas heaters that score 70% or more overall and 70% for their heating score. Note that models in different size ranges can’t be directly compared because heaters with different capacities are designed for different room sizes, so filter by room size or heater capacity (13–15 MJ/h, 18–21 MJ/h or 25 MJ/h) to find the right models for your needs.

Portable or flued heater type. Portable are unflued and need a window or opening somewhere in the room. Flued require installation of a flue kit so the noxious gases can escape from the room.
This is the amount it costs to run the heater based on full blast (highest setting possible) at 3c/MJh.

Most heaters declare the heat output in Kilowatt Hours (kWh). Roughly speaking, 1 kW = 10 square metres of room heating. So if you have a 3 x 4 m room (12 sqm), you'll need a has heater with at least 1.2 kW heating output (12sqm / 10).
Our results table shows the maximum recommended room floor size (assuming a standard ceiling height of 2.4m) in a cool climate. But as well as room size, consider the climate where you live. A model might heat 57m² in a cold climate but 87m² in a mild climate.

Unflued gas heaters must have a stated minimum room volume to ensure they aren't used in a room that's too small, where their waste gas output might be at too high a level. SA, Victoria and WA have further restrictions on the use of this heater type — check with a gas plumber or retailer. We've converted the minimum volume to a minimum floor area in square metres, assuming standard ceiling height of 2.4m.

Note that models in different size ranges can’t be directly compared because heaters with different capacities are designed for different room sizes. Compare each heater against others in the same gas consumption range: small or 11–15 MJ/h, medium or 18–21 MJ/h and large or 25 MJ/h +.

Based on the kW heat output. Room sizes are classified as follows: Small = 29 - 52sqm. Medium = 64 - 90sqm. Large = 65 - 113sqm. There are discrepancies in sizing due to the self regulation of the industry.
The AS4553 Efficiency Star Rating is based on an industry-designed rating scale from 1 to 6 stars. Most models rate very highly in this scheme so it's not as useful as star ratings based on Australian standards, such as those applied to fridges and air conditioners.

Convection (or convector) heaters work by heating the air and letting it circulate up and around through the room (usually pushed by a fan). Radiant-convection heaters radiate heat from an element at the front, so they're best for personal heating (i.e. sitting in front of the heater), but they also produce some heat by convection.
Useful for switching the heater on at certain times (to pre-warm the house before evening, for instance) and to switch it off again automatically.
Important safety feature to prevent curious youngsters fiddling with the controls.
A Similar model is identical in most aspects except for a few. This means that a majority of its test results are identical so you can reasonably expect to get the same results from the model we tested, but for those aspects which aren't identical, we'll note these as "Not Tested" in the Compare tables.
A Tested model refers to a model that is still current and available in the Australian market. You should be able to order this model through your local retailer, or find it online.
These models can't be found in retailers or online or are no longer manufactured. You may still find these models on second hand websites, or in second hand dealers. Test methods may change over time, so criteria which can't be directly compared will contain an N/A.
An Identical model is exactly that. Performance characteristics will be identical and the only difference will be something trivial such as colour, which won't have an impact on performance.
These are models we haven't yet tested but that are available.
