Ancient fire pits were sometimes constructed from the ground, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burned with 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 snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out via a ceiling or wall. These can be put against stone walls, rather than taking up the center of the room, 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 faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. In the later 18th century, Count Rumford made 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 room. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, based upon the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used 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, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated 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 risk. The EPA writes"Smoke may smell good, but it is not great 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 electrical fireboxes.
In the United States, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers 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 an emphasis on the quality of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.32quot; ClassicFlame Spectrafire+ Curved Electric Fireplace Insert 32EF023GRA Video
Some fireplace components include a blower which transports 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 is also enhanced by means of a fireback, a sheet 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 made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric fireplace inserts
