Best Electric Heaters for Australian Homes 2026

Reverse-cycle air conditioning (split system heating mode) is the cheapest per-kWh heating method in Australia — it's 3–5x more efficient than any electric resistance heater. If you don't have a split system, gas heating (ducted or gas log fire) is the next most economical option in Australian states where gas is available. Portable electric heaters have the highest running cost per square metre heated.

Yes, when buying RCM-certified heaters from Australian retailers. Oil-filled column heaters are the safest type — no exposed element. Fan heaters and bar heaters have exposed elements that represent a fire risk if too close to curtains or furniture. ACCC Australian product safety guidelines recommend keeping heaters 1m away from flammable materials and never leaving unattended. Only buy heaters with RCM marking.

For an average Australian bedroom (10–15m²), a 1,500–2,000W heater is appropriate. For a living room (20–30m²), 2,400W is the minimum for adequate warming in southern Australian winters. Panel heaters are more efficient for longer-duration heating in Australian bedrooms; fan heaters are better for quick warmth when you're already in the room.

Gas heating is typically cheaper in Australian states with gas infrastructure (Victoria, NSW, South Australia) — gas costs approximately 3–4c/MJ vs electricity at 7–9c/MJ equivalent heating. However, in Queensland and WA where gas infrastructure is less developed, this comparison changes. Reverse-cycle air conditioning beats both for efficiency. This gap is narrowing as gas prices rise in Australia's east coast market.

Reverse-cycle split system air conditioning is the most effective and economical choice for Australian open-plan living rooms. If a portable heater is needed, a 2,400W fan heater or oil-filled column heater for the seating zone works best. For Australian open-plan areas over 40m², a single portable heater will struggle — prioritise the occupied zone rather than heating the entire space.
