Historical fire pits were sometimes built from the ground, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire 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 coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside via a wall or roof. These can be placed against stone walls, rather than taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as 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 chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces at this time were a sign of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were 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 might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

In the United States, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control problems due to the amount of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and vent all exhaust gasses to 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 more fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Together 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 style 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, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Hanging Your TV over the Fireplace: Yea or Nay? Driven by Decor Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have 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 large as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the initial 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 equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.tv above fireplace
