Historical fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.

Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out via a wall or roof. These can be put against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from 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 also made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to develop and maintain.

In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's design is the foundation for modern kitchens.

The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now were a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the design.

Historically they have been used for heating a dwelling, 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. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not good for you.

Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.

In the USA, some states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues because of the amount of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

AccessoriesFor the inside, common in current Western civilizations comprise grates, fireguards, log boxes, andirons, bark baskets, and fire dogs, all which cradle fuel and accelerate burning. A grate (or flame grate) is a frame, usually of iron bars, to retain fuel to your fire. Heavy metallic firebacks are occasionally utilized to catch and re-radiate heat, to protect the back of the fireplace, and as decoration. Fenders are low metallic frames set before the fireplace to contain embers, soot and ash. For fireplace tending, tools comprise pokers, bellows, tongs, shovels, brushes and tool racks.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their size.

From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.

Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output signal of a fireplace is in case you detect you are turning the thermostat down or up.

Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass window while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace inserts
