caldaia

boiler

noun kahl-DAH-yah Rare

Origin: From Medieval Latin caldaria (vessel for heating), from Latin calidus (hot).

Usage Note

Caldaia refers to a boiler for central heating or industrial steam production. A common false-friend trap: caldaia is NOT caldo (warm/hot) — it shares the Latin root but means the appliance, not the sensation. The annual revisione della caldaia (boiler service) is a legal requirement in Italy for gas-fired systems.

Examples

"La caldaia si è guastata e non abbiamo il riscaldamento."

Natural Translation

The boiler broke down and we have no heating.
