In my old boarding school they tried to keep it off until October half terms, many pupils and teachers was complaining so they were forced to turn on the heating. My bedroom 2 windows was perfect as it face East and South so get sun to warm the room up, the sun leaves at 4pm as it move away. The heating come on at 4pm to 10pm and left on all night if we had snow. After I left and my brother stayed for another 2 years one of the student who studied plumbing decided to fiddle the settings on the radiators in the bedrooms which was hidden inside the tap, he increased the output higher by using his tools and the rooms became much warmer than luke warm, not sure if this effected the gas bill for the school but radiators became hot than warm. Nowadays you get new ones with numbers 1 to 5 and I put at 3 which is correct temperature settings for the room.
