timmmay: I checked my usage - including one oil heater to keep a room from getting too cold I used around 4 units of power between when we go to bed and when the heat pump comes on before we get up. Average usage in a day is 35 - 50 units.
As an aside, on Flick it tells me I've saved 30% compared with what I'd have been on with my last power company. That's better than the average Flick customer saving of 25%, and will get better when I load shift the most of the hot water heating to 3am.
Thanks timmmay, incl a heater, 4kwh sounds reasonable, i think. but then your average usage in a day is way too high. So may be you have a very big home or lot of people or may a little bit mix of both may be ? hmmm i dont know . whats your average power bill ( in kwh and $ ) when you are not using any heaters whatsoever. And also, can you check what was your overnight power consumtion when you didnt use your heater.
sorry for too many questions, but i am just trying to analyse what sort of usage gives what sort of values and so on and so forth .
