Glowworm 208354 Expansion Vessel

Expansion vessels commonly consist of two compartments, separated by a rubber sheet known as diaphragm. In a pressurised system of air and water, shifts in temperature can cause increases and decreases in pressure. The expansion vessel allows the system additional space that can be used when the water expands, this minimises the risk of potentially dangerous pressure levels inside the central heating system.
