Historical fire pits were sometimes built from the ground, within caves, or at 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 toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open flame burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out through a ceiling or wall. These could be placed against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, since they were expensive to build 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 room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficacy, based upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there is frequently 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 serves to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. Some 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 can pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial 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 electrical 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 restricting these types of fireplaces. There are also air quality management issues because of the amount of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the exterior of the structure.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to houses.New Slimline Indoor Electric Fireplaces by Real Flame Camelot Living Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal which 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 complex concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The ideal method to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the first heat is offered through a large glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplaces electric
