Alsatian stove with large exhaust gas heat exchanger, in Fouday church. A stove is an enclosed space in which fuel is burned to heat either the space in which the stove is situated, or items placed on the heated stove itself. There are many types of stoves such as the kitchen stove which is used to cook food, and the wood-burning stove or a coal stove which is typically used for heating a dwelling. Due to concerns about air pollution, efforts have been made to improve the stove design over the years.

Pellet stoves, for example, are a type of clean-burning stove, and air-tight stoves are another type that combust the wood more completely and therefore reduce the amount of the resulted combustion by-products. 1992, all wood stoves being manufactured are required to limit particulate emission. The Old English word stofa meant any individual enclosed space, such as a room, and ‘stove’ is still occasionally used in that sense, as in ‘stoved in’. In its earliest attestation, cooking was done by roasting meat and tubers in an open fire. Pottery and other cooking vessels may be placed directly on an open fire, but setting the vessel on a support, as simple as a base of three stones, resulted in a stove.

The three-stone stove is still widely used around the world. In some areas it developed into a U-shaped dried mud or brick enclosure with the opening in the front for fuel and air, sometimes with a second smaller hole at the rear. A kitchen stove, cooker, or cookstove is a kitchen appliance designed for the purpose of cooking food. The most common stove for heating in the industrial world for almost a century and a half was the coal stove that burned coal.

Coal stoves came in all sizes and shapes and different operating principles. Coal burns at a much higher temperature than wood, and coal stoves must be constructed to resist the high heat levels. A coal stove can burn either wood or coal, but a wood stove might not burn coal unless a grate is supplied. The grate may be removable or an “extra”. This is because coal stoves are fitted with a grate so allowing part of the combustion air to be admitted below the fire. Brown coal and lignites evolve more combustible gases than say anthracite and so need more air above the fire.

Compared to simple open fires, enclosed stoves can offer greater efficiency and control. Enclosing a fire also prevents air from being sucked from the room into the chimney. This can represent a significant loss of heat as an open fireplace can pull away many cubic metres of heated air per hour. Efficiency is generally regarded as the maximum heat output of a stove or fire, and is usually referred to by manufacturers as the difference between heat to the room and heat lost up the chimney. An early improvement was the fire chamber: the fire was enclosed on three sides by masonry walls and covered by an iron plate.
