Cutting the cost

Reverse-cycle is one of the cheapest ways to heat, but only if you run it well. Hold a steady, moderate set-point instead of overheating and then cracking a window. Warm the rooms you're in and shut the doors on the ones you aren't. Clean filters move heat better. If your plan has a cheaper overnight rate, take the chill off early rather than heating hard through the evening peak.
