The price has blown me away too.
But our bill has always been high, as you can see, the previous bill was $688.
Most of my rep heating is simple 40 - 60 watt globes, with only 1 heat cord in the place and that has only been on for the last month, I use flouro lighting for the reps. I blame the fishtanks, all running powerful canister filters (6), water heaters (7), and on the saltwater tank, a further pair of internal pumps and a UV steriliser.
HM was giving three of the tanks a 70% water change weekly which would pump the heating prices up too, as they are all large tanks and the heaters would have been working overtime to reheat the icelandic water coming out of our taps.
Other than a few computers, fridge, washing machine, weekly dryer and normal household lighting, the only other possible source would be the oil heater, but it hasn't been used as much this year as in previous years, so I really don't think that would be the cause. (Last year we ran 2 oil heaters constantly and didn't come anywhere near this).
Things are looking up though as the HM has now moved out (don't worry, he will still be paying his 50%) so the three big tanks have all gone too now, as of today. I will also be calling Energex to look into the account, as I still have my concerns.
I wonder if it is possible to bring an independant person in to survey electricity flow and costs? Does anyone know of such a thing?
