My doubts about watching American TV series: Why do Americans like to build fires in the walls?

Fireplace. After Columbus discovered the New World in 1492, America became a place where people from European countries went to open up wasteland. People who immigrated to North America (then a British colony) won the War of Independence from Britain in 1776 and founded the United States. Since all the people at that time were European (mainly British) immigrants, their living habits were also British. In ancient Britain, it was customary to build a fireplace in the wall for heating, boiling water, and cooking. In the days of wood as fuel, it was a great convenience to have the stove built into an exterior wall. The ash removal port is opened from the outside to facilitate the removal of ash. Today, although the function of boiling water and cooking food is no longer available, it can still be used for heating. At the same time, people have a special yearning for fire. A safe fire in the house in winter creates a warm and comfortable feeling. The smoke from burning wood spreads lightly outside the house and smells good.
