zhuyan:timmmay: The heater will be costing about 55c/day if it's run for two hours, so $15/month.
Hot water uses around 1/3 of most peoples power, heating 1/3, and the rest appliances. It's not heating, so I have to guess hot water. Is there a leak? Check the roof to see if it's overflowing out the top. How long do people shower for each day?
My last power bill was $300 or so, actual read. My house is old but well insulated, and we have a huge but efficient heat pump on 21 degrees from 5pm until 10pm, then on 17 degrees from 10pm until 7am. Weekends we don't turn it off. We also run another heat pump for a short time each day, a fan heater in my office, and an oil heater on low in the bedroom. We have computers on, a big TV and AV system. There's two people living in the house, and we have two showers a day each. So your $350 for three people and no heating sounds way too high.
$300 for all that is not bad at all and is actually quite impressive? Which power company are you with and what plan?
I'm with Empower and am on a Day/Night Low User Plan, which means my hot water cylinder is not hooked up with power between 7am and 9pm every day. There are two people living in the house so you see having two showers a day each (4 showers) would be mission impossible for us as the hot water simply runs out.
We have only one standard size heat pump in the lounge and we have it on like 25 degrees between 6-11pm and then turn it off. On weekends, we have it on from 11am until 11pm. In the bedroom we have one electric heater which we turn on for about 1 hour before sleep. Apart from that, just usual whiteware, 40" TV plus ps3.
The latest bill just arrived today and it showed $316.
I probably need to switch power company shortly.
Meridian I think, standard plan. My hot water's allowed to heat any time. I've done a lot of work on efficiency, lots of insulation top bottom and sides, retrofit double glazing.
25 degrees is pretty warm, the higher you go the higher the heat loss. I prefer to wear two layers and keep it at 20-22 and save the money.
