Every time we put on the central heating and/or hot water water pours out of the overflow. There is no leak from the overflow at any other time. There is also a lot of air that collects in 1 particular radiator upstairs requiring it to be vented on an almost daily basis. All the rads & hot water get hot so there is no problem there.
Heating system is a standard vented system.
Job is to fix this problem
