Reverse-Cycle vs. Old-School Heaters: The Winter Bill Smackdown

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.
