Historical fire pits were sometimes constructed in the floor, in caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burnt with the smoke rising to 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 stop smoke from dispersing a room and vent it outside through a ceiling or wall. These can be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as 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 enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now were a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, 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 gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, several states and local counties have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues due to the amount of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Top 60 Best Fireplace Mantel Designs Interior Surround Ideas Video
Some fireplace units include a blower that 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 can also be increased with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. The best method to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the first heat is provided through a large glass window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace surround ideas
