Solar Expansion Vessels

When a liquid's temperature changes in a closed system, like a solar installation, it requires an expansion vessel. However, there are distinct variations between solar systems and central heating systems regarding the placement of the expansion vessel and the required capacity calculation. This is primarily because of the medium used and the way solar systems operate.
