Reduce the damp

A damp home is bad for your health and uses more energy to heat. Put a ground moisture barrier under your house to keep the dampness out.

Draw your curtains

Draw your curtains 30 minutes before sunset to conserve heat and close doors to the rooms you don’t need to heat.

Stop the drafts

Use door snakes to stop any drafts coming in under the doors and fix any gaps in the walls or around your windows.

Changing lightbulbs

LED light bulbs use 85% less power and can last 15 times longer than incandescent bulbs. This means you buy light bulbs less often and use less power when the lights are on!

Ventilate the laundry

Make sure your laundry room is well-ventilated otherwise your dryer is forced to use the damp air it expels, which takes longer to dry your clothes and your power bill increases.

Check appliance seals

Fridges, freezers and ovens with worn door seals use unnecessary power. Most appliance centres supply and fit replacement seals.

Stop the drip

One leaking hot tap can use around $40 in unnecessary power throughout the year. This can be easily solved by replacing the washers in any dripping taps.
