As you know, an "open expansion tank" is a storage tank at the roof of buildings that is at atmosphere pressure and is used to adjust the pressure of the central heating systems. It means when water became hot its volume increases, and this increased volume go to" the open expansion tank" to prevent from increase of the loop pressure and when water became cold and it's volume decreased, the water leave the "open expansion tank" to ncrease the pressure and prevent from the minus pressure.
