A fireplace or hearth is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design. Historically, they were used for heating a dwelling, cooking, and heating water for laundry and
A Franklin stove. The Franklin stove is a metal-lined fireplace named after Benjamin Franklin, who invented it in 1742. [1] It had a hollow baffle near the rear (to transfer more heat from the fire to a room's air) and relied on an "inverted siphon" to draw the fire's hot fumes around the baffle. [2]
The fireplace insert was invented in 1742 by Benjamin Franklin, which he called 'The Pennsylvania Fireplace' (also known as the Franklin Stove), in the United States.He came upon the idea as a means of using coke (a smokeless fuel made by the destructive distillation of certain types of coal) and incorporated the use of an electric blower to improve efficiency.
A major improvement in fuel technology came with the advent of gas. The first gas stoves were developed as early as the 1820s, but these remained isolated experiments. James Sharp patented a gas stove in Northampton, England, in 1826 and opened a gas stove factory in 1836. His invention was marketed by the firm Smith & Philips from 1828.
Large quantities of burned bone and moderately heated soil lumps were found, and the cut marks found on the bones suggest that butchering and prey-defleshing took place near fireplaces. [29] In addition, hominins living in Qesem cave managed to heat their flint to varying temperatures before knapping it into different tools.

In 1743, Benjamin Franklin invented an all-metal fireplace with an attempt to improve the efficiency. It was still an open-faced fireplace, but improved on efficiency compared to old-fashioned fireplaces. Some stoves use a catalytic converter, which causes combustion of the gas and smoke particles not previously burned.
At the time, gas central heating had yet to be developed, so people relied on burning coal or wood as their main source of heating. [8] [9]Parker felt that the fireplace was not enough to keep her and her home warm during the cold New Jersey winter, and designed the first gas furnace that was powered by natural gas and the first heating system to contain individually controlled air ducts that ...
