Question 1 of 27070

Expansion tanks when used in a ship's low temperature hot water heating system may be of the open or closed type. In a closed type system, what would be the normal temperature range of the water?

🔍 Key Concepts

• Relationship between system pressure and boiling point of water in a closed heating system • Typical operating temperature range for low temperature hot water (LTHW) systems on ships • Why very high water temperatures can create safety and material stress issues in piping and equipment

💭 Think About

• Think about the approximate boiling point of water at atmospheric pressure and how a closed system under pressure changes that temperature. • Ask yourself: in a "low temperature" hot water system, which of these ranges still seems reasonable for continuous operation without excessive risk of boiling or damage? • Compare the listed ranges to what you might expect from a building’s or ship’s normal hot water heating system, not a high‑temperature or steam system.

✅ Before You Answer

• Eliminate any ranges where water would be near steam plant temperatures, which are not typical for LTHW systems. • Consider which range would allow safe circulation without flash boiling in a pressurized but relatively low‑temperature system. • Verify which range sounds like common heating system supply temperatures (not process or propulsion temperatures).
