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 exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These could be put against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were 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. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied 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 still placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they were used for heating a dwelling, 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 (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, 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 route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
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 good, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the USA, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth 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 based within a space, allowing more people to gather around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which has been 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 size.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.Electric Fireplace TV Stands Walmart.com Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that sits behind the fire 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 efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. The best way to estimate the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered 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 offered through a large glass while the flame is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace tv stands
