Except your house is heated by literally anything that's doing anything inside it (like your own body, cooking, using a computer, taking a shower, ...), meaning it never reaches the outside temperature except if it's inhabited for a long period of time. Meaning cooling have to compensate for every bit of activity, whereas heating doesn't.
- dghughes 8y agoPlus people here have to learn that insulation is for hot or cold. Many people open their windows on hot days then complain it's hot in their houses. It wouldn't take as much energy if people would close their windows. And my dad leaves the AC on all day. I said just turn it on ten minutes before you go in the room it will probably do the same and be cheaper.
- ant6n 8y agoHeating in Canada will use ~kW, in the summer I'm not using any device in that order of magnitude, including humans (which are what, 100W?). If I remember correctly, the energy use of heating/cooling is related to the square of the temperature difference, so if ACs with a low temperature delta use nearly as much energy as heating does in winter, with its higher delta, it indicates that there may be a lot of waste.
