I recently moved into a 3-bedroom unit with a friend. There are only two of us but we somehow managed to used $190 of gas in 41 days. I think it was mainly due to the excessive use ( IMO) of heating. My housemate is extremely sensitive of the cold and she turns the heating on whenever she is home, while I would walk around in short-sleeves. Sometimes she forgets to turn the heating off and leaves it on overnight.I know summer is coming up, however the warmer days last week did not stop her from turning the heater on.
The bill obviously gave me a shock and got me started thinking whether it is worth getting her an electric heater, that would mean she would just turn it on in her room when she wants, instead of turning the heating on for the whole house. But then, it also means I would have less control over how often heating is turned on. Obviously electricity is more expensive. ( We are paying about $40 pm atm)
Check the service costs of Gas.. you'll likely find that half or more of your bill is just to have it supplied to your place before using anything at all!
Then work out the costs of running an electric heater.. It's going to chew through 30c/hour at least (for a 1000W heater) so on a timer switch for 8 hours a day it's going to cost and extra $2.40/day… over 90 days that's $216…
Lots of assumptions in there, but the answer is probably no… Electric heating is ludicrously expensive especially if you have Gas connected and in use for Cooking/Water Heating.
