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? Illustration GS-0151 oo

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

Low-temperature hot water heating systems typically operate within the 180F to 200F range. This temperature is sufficient for effective heat transfer in marine radiators or air handling units while remaining safely below the boiling point at standard operating pressures, minimizing the risk of steam formation in the piping.
