Ideal 177601 Expansion Vessel Kit\n\nEffective pressure control is essential for maintaining the reliability, efficiency, and safety of a sealed heating system. The expansion vessel contains an internal diaphragm that separates system water from a pre-charged air chamber, allowing pressure changes to be absorbed gradually as temperatures fluctuate. Without a correctly functioning expansion vessel, system pressure can rise rapidly when heating is active, often leading to activation of the pressure relief valve, water discharge, and frequent loss of system pressure once the boiler cools.\n\nOver time, expansion vessels may lose their air charge or suffer diaphragm fatigue, reducing their ability to manage pressure changes effectively. This can result in repeated pressure faults, visible discharge from the safety valve, or the need for frequent system re-pressurisation. Replacing a weakened or failed expansion vessel with this kit helps restore stable pressure control, improves overall .
