I set my temperature at 25. Appliances I use daily are a fridge (24 hours), laptop (5 hours max), a hair dryer (less than 5 mins), water heater (15 mins)… that's all I can think of, and have been the same since I moved in, meaning seven years ago, and until these two months I saw the bill goes up, and that concerned me. If it's because we no longer enjoy the subsidy, I'm perfectly fine. Just wanna fix  issue before it's too late, if really there is any.
