Zilmet Expansion Vessels 

Expansion vessels absorb water volume variations in closed heating systems to maintain constant system pressure, whilst also helping to reduce energy consumption. 

An increase in water volume due to an increase in temperature is absorbed by the expansion vessel, then returned to the system as the temperature decreases. 

Available from ADEY in various sizes to suit different system volumes.
