Historical fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.

Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be put against rock walls, rather than taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were expensive to develop and maintain.

Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's design is the basis for modern fireplaces.

The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a sign of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.

Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues due to the quantity of moisture that they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and vent all exhaust gasses into the exterior of the structure.

AccessoriesFor the interior, common in recent Western cultures include grates, fireguards, log boxes, andirons, bark baskets, and fire puppies, all of which cradle gas and quicken burning. A grate (or fire grate) is a framework, usually of iron bars, to retain fuel for a fire. Heavy metal firebacks are occasionally utilized to capture and re-radiate warmth, to safeguard the rear of the fireplace, and as decoration. Fenders are low metallic frames set before the fireplace to contain embers, soot and ashes.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a room, allowing more people to collect around it.

From the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with ornamental tiles.

Some fireplace units include a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. The best way to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.

Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is provided through a big glass window while the flame is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.napoleon fireplace
