A boiler expansion vessel absorbs pressure changes as water heats up and expands. It keeps system pressure stable and helps protect valves and seals. When the vessel loses charge or fails, pressure rises fast when heating runs. Then pressure can drop again after cooling. You may need to top up often, or the safety valve may drip. Replace the correct expansion vessel to keep pressure steady and improve reliability.
