In later Middle Ages, building chimneys were part of an increasing royal expenditure. Often, this was a reward for knights who performed service for the king. The nobles were quick to imitate the king in enjoying the new technology.

It shows that the poor were also beginning to introduce the new heating technology into their homes. Gradually the connection between warmth, comfort and privacy applied to people in all levels of the economic and social scale.
