Expansion vessels are designed to absorb heat expansion of the heat carrier in closed heating systems. The main purpose of the expansion vessel is to compensate for a change in the volume of water due to the change in temperature in heating systems. For example, when heating the water from 0 to 100 ° C, it increases its volume by about 4.5%. This means there must be space inside the system to keep it free from leaks and ruptures.
