When the Aussie winter bites, it’s tempting to drag out that old bar heater or switch on the trusty oil column. But here’s a shocker: those “classic” heaters can burn up to three times more power than a modern reverse-cycle split system!
Let’s do the numbers:
- Bar (2kW):
Runs at ~2,000W—costs about $0.66 per hour (at 33c/kWh). Use it 5 hours a night, 3 months of winter? That’s over $300 for one room. - Reverse-Cycle Split System (heating mode):
Same comfort, but only draws about 600–700W—costs $0.20–$0.23 per hour. Same usage? You’re looking at around $100.
That’s a saving of $200–$250 every winter—and that’s just for one room!
Quick Win:
- Set your reverse-cycle at 19–21°C.
- Keep doors closed and curtains drawn for max warmth.
- Clean the filter before winter starts.
Spot the drainer:
- Old heater glowing red?
- No thermostat or timer?
- Feels warm up close, but cold everywhere else?
If yes, you’re heating your bill, not your home.
