How to Choose the Best Expansion Vessel...
Have you ever heard a water heating system referred to as ‘closed’? The reason for this is that such systems are not exposed to the ordinary pressure of the atmosphere surrounding us. When the water inside a closed system is heated or allowed to cool, the pressure within is subject to sudden changes which create ‘water hammers’, which are changes in the direction of or complete stops of water flow. These damage the system and the way to avoid the problem is installing a high quality expansion vessel.
 
 

It is simply air that is used to solve the problem - expansion vessels contain a regulated amount of air which cushions any impacts from the water hammers naturally created during heating and cooling processes. Expansion vessels are not only used in domestic settings - they can also be found in many pieces of industrial equipment and in car engines. Pressure is absorbed, impact softened and protection ensured when an expansion vessel is correctly installed.
