do you know how much you are using the R/C a/c heater per day? I was told to have the a/c at 24 degrees in summer, to save electricity. I use a tower heater (like a tall blow heater) for winter, my only option, and have been told to have that at no warmer than 21 degrees (to save electricity), i usually have it at 19 degrees. It has a timer on it, which i turn on EVERY time, e.g for one hour, i'm so scared i might leave heater on one day by mistake.

i'm using - wearing ALOT of clothing, including outside parka, - blanket on me when sitting down e.g watching tv - having hot quick shower at night - to reduce the amount of time i have a heater on. My place has zero wall insulation, it's really cold. Very small rooms, have to keep doors closed always so i'm just heating ONE space at a time.

So many draughts and cracks (in a rental), and no wall insulation, there's not much i can do to improve the electricity efficiency. I've wasted money on adhesive anti draught stuff that just fell off. Door snakes. I put roof insulation in, but still it's so cold, even in the day, cold enough to want to wear gloves just to type on computer.
