With a brisk autumnal chill beginning to roll out, we’re finally bringing our cosy essentials out of hibernation. And while everyone’s approach to seasonal shifts differs slightly, we personally consider warming staples like plush quilts, heated throws, cosy bed linen, and, most importantly, great gas heaters, as non-negotiables for this time of year.
Natural gas heaters, in particular, are great at beating the winter chills and working fast; functions you’ll soon be very grateful for. And yes, most of us wait for the coldest months to hit before investing in heating solutions, but this isn’t exactly the smartest tactic. You see, the earlier you shop, the more likely you are to pick up a great deal, like saving $868 on our top gas heater recommendation of 2026.

What you need to know before buying a gas heater
The best gas heater in Australia for 2026 is typically a high-efficiency model like the Rinnai Dynamo Natural Gas Heater DY15N, known for reliability and strong heat output. Look for models with the right kW rating and safety features for your space.
Yes, gas heaters are often cheaper to run than electric heaters in Australia due to lower energy costs per kWh equivalent. Running costs still depend on usage, insulation, and heater efficiency.
You need roughly 1kW of heating power for every 10 square metres of space. Choosing the correct size ensures efficient heating without wasting energy.
Yes, indoor gas heaters are safe when properly installed and maintained, especially flued models that vent emissions. Always use a licensed gas fitter and install carbon monoxide alarms.
Flued gas heaters vent fumes outside, while unflued heaters release small amounts of emissions into the room. Flued models are generally safer and better for long-term indoor use.
Yes, portable gas heaters are ideal for flexibility and smaller spaces, especially if you need occasional heating. They require proper ventilation and a gas connection point to operate safely.
Flued gas heaters and modern ducted systems are typically the most energy-efficient options. They provide controlled heating while minimising heat loss and indoor emissions.
Yes, but only if it is a flued model or specifically approved for indoor overnight use. Unflued heaters are generally not recommended for bedrooms due to ventilation concerns.
Gas heaters typically last 10–20 years with proper maintenance and servicing. Regular servicing every couple of years helps extend lifespan and maintain efficiency.
Look for features like thermostat control, timer settings, oxygen depletion sensors, and flame failure shut-off. These improve safety, efficiency, and ease of use.
Gas heaters are generally cheaper to run (compared to electric heaters) as they can heat large open-plan spaces quickly. In contrast, electric heaters are generally designed to heat smaller spaces and take a bit longer to heat the entire room.
