Think your biggest energy bill culprit is the aircon, or the dryer? Think again—it might be that old fridge humming away in the kitchen or garage.
If your fridge is more than 10–12 years old, it could be quietly adding $80–$150 to your bill every year. That’s more than a month’s worth of groceries!
Why are old fridges so power-hungry?
Spot the drainer:
What’s the real difference?
A brand new 4–5 star 400L fridge can use as little as 220 kWh/year (that’s about $72 a year at 33c/kWh), while an older 400L fridge can use over 450 kWh ($148/year).
Over five years, that’s a $380 saving—often enough to pay for most of a new fridge.
