Usage Note

Heating is an uncountable noun — you cannot say 'a heating' or 'heatings'. It refers to the entire system in a building. A single device that produces heat is called a heater (e.g., an electric heater in one room). A specific type of whole-building system is central heating, which uses one main heat source (a boiler) to warm the entire building.

Common Mistakes

The heater in this building is broken.' (when you mean the whole system)
The heating in this building is broken.
heater means a single device; heating means the whole system.

Synonym discussion

Sense: noun/1

Heating is the broad, general term for the whole system that warms a building — including the boiler, pipes, radiators, and controls. Central heating specifies a particular design: one central boiler that heats water and sends it through pipes to radiators in multiple rooms. A heater is a single, often portable, device that produces heat in one spot (e.g., a fan heater or oil-filled radiator). A radiator is the visible metal panel in a room that gives off heat, but it is only one part of a heating system. In everyday conversation, 'turn the heating on' refers to the whole system, while 'turn the radiator on' focuses on one room's output.

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

Heating comes from the verb heat, which traces back to Old English hǣtan ('to make hot'), from Proto-Germanic *haitijaną. The -ing suffix turns the verb into a noun referring to the system or process of supplying warmth. This noun sense of 'heating' (as an installed system) became common in the 19th century with the spread of central heating technology.
