For ESL learners
"heater" means: A device that produces and radiates heat, typically to raise the temperature of a room or building.. Register: neutral, standard English, usable in most everyday contexts. A common non-native mistake is to use the word in the wrong register, or to assume one fixed meaning when it is actually polysemous; always check the surrounding register and the audience before producing it yourself. In formal writing, prefer a neutral synonym or a short descriptive phrase, and use this word only when you have heard or read it being used naturally in a comparable context.

A person who heats something, for example in metalworking.
“First you've got to sit up and go into the tackroom, because you are soaking wet. And shivering.” The tackroom was cold, so Sam turned on the kerosene heater and found a wool cooler and wrapped her in it.

For specific readers
Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
