Use reverse-cycle air conditioning

Reverse cycle air conditioners are the most cost-effective way of heating and cooling your home.

They typically use just 25-30% of the energy required by conventional gas or electric systems. Power your reverse cycle air conditioner with solar if you have it or with greenpower through your electricity provider to make it zero emissions.
