gas heating (floor-by-floor)
Natural-gas heating with an individual burner serving a room, space, or floor rather than central ducted distribution.
Floor-by-floor gas heating describes a system where individual rooms, spaces, or floors in a building are heated by a single natural gas burner. This system is distinguished from central heating, which distributes its heat to various rooms through forced air ducts.
A room or separate space is included alongside an entire floor. The name does not require every burner to serve exactly one complete story.
Central gas heating supplies multiple rooms or floors through ducts. This entry identifies the individual local burner arrangement.
