Are you planning for an open-plan living room? Well it isn’t about buying the biggest model. You must buy the right indoor gas heater. Check your room size & ceiling height. Also insulation, windows, & climate and layout are critical considerations. All these affect how much heating power you need. A correctly sized heater can provide more consistent warmth. Meanwhile, an undersized/oversized device may affect comfort & running costs.
Are you aware of the 1st step? It is to calculate the area you want to heat. Measure the length & width of your space. Multiply them. You will be left with the floor area(sq mt).
Many Aussie people use 1kW of heat output for every 10m². This is seen in a reasonably insulated room with normal ceilings. Still, this is just 1 quotation. Climate, insulation, glazing & ceiling height can change the necessary capacity.
For open-plan spaces, people must consider the entire area. You can just assess only around the sofa / dining table.
Natural Gas Heaters Indoor Size Guide for Open-Plan Areas
Every home is different. The below ranges provide a base-
| Approx. Area | Indicative Heat Output |
| Up to 30m² | Around 3kW |
| 30–40m² | Around 3–4.5kW |
| 40–60m² | Around 4.5–6.5kW |
| 60–80m² | Around 6–8kW |
| 80m²+ | 8kW+ or another heating solution |
These figures are indicative. These can’t replace professional sizing. Manufacturer recommendations can vary between models.
Floor area is 1 part of calculation when choosing gas heaters for house. A room with a 3m ceiling contains substantially more air. One with a standard 2.4m ceiling will have less.
This is important in houses with raked ceilings or large open-plan spaces. In these situations, calculating room volume-length × width × ceiling height is important. This will provide a better starting point.
Does your living area have unusually high ceilings? Then, you can talk about the required output with a qualified professional. You can’t solely depend on a normal room-size chart.
A well-insulated home holds warmth for longer. This can cut the heating capacity required. Poor insulation allows heat to escape more quickly. This means you need a higher-output appliance.
Large windows, sliding doors & too much glass can increase heat loss. This is mainly faced during winter. Curtains & suitable window coverings retain warmth. But important glazing should still be thought of when buying a heater.
The same-sized living room may need different heating capacity. This hinges on where you live in Australia. Colder climates require more heating output than milder regions.
Open-plan kitchens, dining areas & living rooms are harder to heat. These are not like enclosed rooms. This is because warm air can move into bordering areas. Hallways & staircases can affect how quickly the room reaches your desired temperature.
Always be extra careful about the difference between kW output & MJ/h gas input.
MJ/h indicates how much gas the appliance consumes. Meanwhile, kW output indicates the heat delivered by the heater. Are you checking out different models? Then, look at the heat output & manufacturer-rated heating area. Thus, you can do a better comparison.
A higher gas input doesn’t mean a heater can deliver more practical heat.
A portable gas heater indoor can be convenient for certain applications. But you can’t consider this for a large open-plan area.
Unflued gas appliances have specific ventilation. They also come with minimum-room requirements. These vary according to appliance & state or territory rules. Permanent ventilation openings are required for unflued gas space heaters. Always speak with a licensed gas fitter before set up.
For bigger areas, homeowners may consider appropriately sized flued gas heaters or gas fireplaces.
The right indoor gas heater should match your accommodation’s floor area. Ceiling height, insulation, & glazing influence heating performance. Plus, the climate & the openness of the layout are critical considerations. Don’t select from gas heaters for house applications. Compare the manufacturer’s specifications. Get professional advice if needed.

Flued gas heaters are the safer choice for indoor use. This is because combustion gases are expelled outside. Room-sealed flued models provide the highest level of protection. Unflued or portable gas heaters require adequate ventilation. These are restricted in some Aussie states and territories. So, check local requirements & the manufacturer’s instructions.
The best gas heater depends on the room size & insulation. Plus, you can monitor ceiling height, layout & local rules. A properly installed flued can be a suitable option. This is also the case with a room-sealed gas heater. A licensed professional can choose the appropriate model & heating capacity.
There is no single best indoor gas heater for every Aussie home. The right option hinges on heating requirements & room size. Plus the gas type, efficiency, & installation options are important considerations. Compare the manufacturer’s specifications. Then, choose an appropriately sized.
Portable LPG gas heaters should only be used indoors. This can be an option if the appliance is approved for indoor use. And for this, all ventilation & safety requirements need to meet. Many portable gas heaters are unflued. These require ventilation. Meanwhile, some outdoor LPG heaters must never be used indoors. House owners must stick to the manufacturer’s instruction.
