Draught dodging: A lot of heat is lost through windows, so cover them up with close-fitting curtains or blinds. Plug up  gaps under doors with draught stoppers or door snakes. The most effective way to seal in your home’s heat, though, is through insulation—it cuts heating costs up to 40 percent.

Gas over electric: Gas is cheaper to run, it produces less emissions, and gives off more heat than electric heaters. Reverse-cycle air conditioning is the most efficient of electric heaters and slow combustion wood heaters are the pick of wood-based types. When buying a heater, always aim for one with the highest energy star rating.

21 and under: The ideal temperature for a heated room in winter is 18-21 degrees. For every degree above that, the cost of your heating bill increases 10 percent, so it’s smarter to put on a jumper for extra warmth.

Blanket solution: If you like your bed to be toasty warm before you get into it, opt for an electric blanket as it uses much less energy than room heaters.

Doors closing: Keep doors to empty rooms closed when you’ve got a heater on, especially bathrooms that have exhaust fans.

Keep Your Cup

Getting a takeaway coffee or tea is a daily ritual for hundreds of thousands of Australians that costs our environment dearly. Thankfully, a more sustainable alternative has arrived. KeepCups are a reusable cup made from polypropylene. It comes in three barista-standard sizes, while the splashproof lid meets OH&S standards. KeepCups have an estimated lifespan of four years and can then be recycled. Check them out at www.keepcup.com.au or ask your local café to order some in.
