AIBU to be complaining that we have central heating on downstairs whilst my partner lets our 3 children have their bedroom windows open? The heating is set to 21 degrees, it’s between 6 and 12 degrees outside depending on the time of day and in some cases they have them slightly open and in other cases they have them wide open. She says because their bedroom doors are shut it’s not wasting power or cooling the house down but we do have gaps under their doors. My issue is they’re cooling the rest of the house down and it’s also a complete waste of money.
