Reticulated gas price is my largest gripe on my power bill. I have no idea why gas is so expensive especially the daily charge that now exceeds 1$/day whether you use it or now.
My plan over the summer is to rip out gas and replace my gas hot water cylinder with an electric one. The hear pump I installed last summer has a running cost of approx half of the flued gas heater. No brainer.
Which model flued gas heater do you have? And can you switch to electric hot water while still keeping your power usage below 8000 units per year or 666 units per month? If not then you will need to move to an electricity plan that has more expensive daily charges. At least $1.60 per day just for electricity.
