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

Standard marine low temperature hot water heating systems operate safely below flash points and excessive pressures, typically maintaining supply water temperatures between 180F and 200F. This thermal range prevents localized boiling while providing adequate heat transfer across shipboard terminal units.
