What is the main purpose of the Feed and Expansion (F&E) cistern in an open vented system?

• To provide a safety outlet in case of system overheating

• To allow the heated water to expand and operate at atmospheric pressure

• To separate air from the system and reduce noise

• To discharge pressure to a safe location if required

What is the function of the open vent pipe in a heating system?

• To discharge pressure to a safe location if required

• To separate air from the system and reduce noise

• To allow the air to escape from the system while filling with water and in operation

• To provide a safety outlet in case of system overheating

What is the purpose of the sealed expansion vessel in a sealed system?

• To replace the feed and expansion cistern of the open system

• To provide a safety outlet in case of system overheating
