I also don't really get the "what temperature is your house?" type questions.
As has been pointed out upthread, houses are all different. The outside temperature varies depending on your location. Some houses are very draughty, some are detached with single glazing, some are very well insulated. Whether I have the heating on (or not) depends on what I have been doing. If I am sitting sewing then I will get colder a lot quicker than if I have been in the garden sweeping up leaves/doing the hoovering/cleaning the windows etc etc.
Even if you get 100 replies saying 15, 20, 22, 8 degrees (other temperatures are available) then so what? I keep the heating at a level which is comfortable/affordable for me.
Also "how much do you spend on electricity a day?" Well it depends if I am doing the washing, baking bread, using the jet washer or just sitting browsing on MN. My water is heated by gas so it will be a very different figure from someone who has an immersion heater or someone who has an electric hob.
There is no "one size fits all" and there are so many variables that the answers are meaningless.
Nothing wrong with all the threads with useful tips for keeping bills low, but knowing the temperature of the home of a complete stranger is not particularly useful (and we have no way of knowing whether it is made up in the first place anyway).
