Summer Power Saving Tips

Here are some tips to make your house feel like a home and not an oven on hot days, without sending your electricity bill or your greenhouse gas emissions through the roof.

  1. On hot days, heat comes straight through unprotected windows Shade your north and west facing windows.
  2. A bit of strategic opening and shutting can make a big difference. Shut your windows and curtains on hot days. Open up the house when it gets cool in the evening and use thick curtains with block out backing or solid blinds.
  3. Shut the door to particualrly hot areas so they don’t heat the rest of the house.
  4. Use a fan first instead of turning on the cooling. Fans are a good money and power saving tip costing virtually nothing to run.
  5. Set your thermostat to 26°C, which should keep your home comfortable and save you money. Setting your thermostat just 1° cooler can up your cooling bill by 15%.
  6. Just cool the room you’re in to save lots of energy, and give your cooler a chance to work properly, instead of trying to cool a bigger area. Shut the doors to this room and seal the gaps so the cool air doesn’t escape.
  7. Get some insulation which doesn’t just keep your house warm in winter, but also keeps it cool in summer, particularly if you combine bulk insulation (big batts) with foil insulation (thin sheets). Ceiling insulation can cut energy usage by 45%, paying for itself in reduced energy bills. 
  8. Enjoy the great outdoors when it gets cooler in the evenings.
  9. Avoid using halogen lights, dishwashers, cooking appliances and dryers which all produce heat during the hottest part of the day
  10. Look after your air conditioner - keep the outdoor bit of it shaded (e.g. with plants) and clean filters regularly.
