Ancient fire pits were sometimes built in the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burnt with the smoke rising to 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.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it out via a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer place at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected into 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 also deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves 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 metallic liners than with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, several states and local businesses have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management issues due to the amount of moisture that they discharge into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that's heated, and port all exhaust gasses into the outside of the structure.

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

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was fire burned, and was built of cast iron frequently backed with decorative tiles.

Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use 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 can also be manufactured from stainless steel. Efficiency is a complex notion 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, designed to warm the atmosphere. The ideal 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 though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.lowes fireplace
