Expansion tanks when used in a ship's low temperature hot water heating system may be of the open or closed type. Referring to the illustrated central-station hookup for a hot-water heating system drawing, what would be the normal temperature range of the water? See Illustration GS-0151 oo

Correct Answer: Option A — 180F to 200F oo

Low-temperature hot water heating systems typically operate within the 180°F to 200°F range. This temperature is sufficient for effective heat transfer in shipboard radiators or convectors while remaining safely below the boiling point at standard operating pressures, minimizing the risk of flashing and cavitation within the circulating pump system.
