Ancient fire pits were sometimes built from the floor, within 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 early indoor flame pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out through a ceiling or wall. These can be placed against rock walls, rather than taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, as they were more expensive to build 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 area at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now were a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house 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 casting 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 out of the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture that they discharge in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually centered within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into houses.CASTLECREEK® Media Center Fireplace 420855, Fireplaces at Sportsmans Guide Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the first heat is provided through a big glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.media fireplace
