Ancient fire pits were sometimes constructed from the floor, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where an open fire burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be put against stone walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, since they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier place at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now have been a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the design.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as 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 good, but it is 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 either wood or gas or retrofit with log inserts or electric fireboxes.
In the United States, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control issues due to the amount of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 components, the surround and the insert. The encircle comprised 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. As well as providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.Empire Tahoe Deluxe Direct Vent Natural Gas Fireplace 36quot; DVD36FP30N Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also 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 made from cast iron, but are also made from stainless steel. Efficiency is a complicated notion although 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 atmosphere. The ideal way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have 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 large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the first heat is provided through a big glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.direct vent gas fireplace
