heater
B1Neutral to Informal (depending on context). Technical/formal for device specifications; informal/slang for sports/gun meanings.
Definition
Meaning
A device for heating air or water in a room, building, or vehicle.
A device or person that provides warmth; in sports slang, a very fast pitch (baseball) or shot (squash/hockey); in electronics, a filament or element that produces heat within a device; informally, a gun.
Linguistics
Semantic Notes
Primarily a countable noun. The core meaning (appliance) is literal. Extended meanings are metaphorical (e.g., a fast pitch 'heats up' the game) or slang (gun as a 'heater').
Dialectal Variation
British vs American Usage
Differences
Minor. UK speakers may be more specific ('immersion heater', 'storage heater'). 'Heater' for a car's heating system is common in both, but US may use 'heater' more broadly for any space heating unit. The sports slang for a fast pitch is predominantly American.
Connotations
Neutral for the appliance. The slang 'heater' for a gun carries a strong underworld/crime connotation.
Frequency
Very high frequency for the core meaning in both varieties. Slang uses are low-frequency outside specific contexts.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'обогреватель' (space heater) and 'нагреватель' (heater for liquids/general). Both are valid translations depending on type.
- The slang for gun ('heater') has no direct equivalent in this sense; using 'обогреватель' for a gun would be nonsense.
Common Mistakes
- Using uncountable form: 'We need more heater.' (Incorrect) -> 'We need another heater.' (Correct)
- Confusing 'heater' (device) with 'heating' (the system or process): 'The house heater is central.' is less common than 'The house has central heating.'
