Coal-fired heating systems required chimneys to vent combustion fumes.
The number of chimneys on a house indicated the number of fireplaces or stoves that were installed.
Wealthy Victorian families often had multiple fireplaces in their homes, each requiring its own chimney.
Chimneys also served as status symbols.
The more chimneys a house had, the more wealthy and affluent the family that lived there was assumed to be.
