Historical fire pits were sometimes constructed in the floor, within caves, or in the middle 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 generated hazardous or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier area at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house 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, where the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality management problems due to the quantity of moisture that they release into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and port all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.Ameriwood Home Parsons Electric Fireplace TV Stand for TVs up to 65quot;, Black eBay 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 lower heating load. Fireplace efficiency can also be enhanced with the use 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 made 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 warm the air. The best way to estimate the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. 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 modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified 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 offered through a large glass while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.black fireplace tv stand
