the rad in my daughters room (hot water - 1950) keeps airlocking, her room is on the top floor, only two heaters on the top floor. the other one does not airlock. i have to bleed her heater every couple of days and soometimes she wakes up at 2 am and her room is cold and cries.
how do i stop the constant airlocking?
