furnace + noun (attributive)

用法筆記

This sense is more common in American English. In British English, 'boiler' is typically used instead when the system heats water for radiators. 'Furnace' in this sense refers specifically to the heat-producing unit, not the whole heating system. The metaphorical simile 'like a furnace' (meaning very hot) is common in informal speech: 'This room is like a furnace!'

常見錯誤

❌I turned on the furnace to cook dinner.
✅I turned on the furnace to warm the house.
💡A building furnace heats indoor air or water; it is not the same as a stove or oven for cooking.
