Historical fire pits were sometimes built from the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a ceiling or wall. These could be placed against stone walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, as they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout 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. Instead it depended on simple designs 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 stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, based upon the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's 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 serves to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. Some 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 various studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell great, but it is 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 either wood or gas or retrofit with log inserts or electrical fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues because of the quantity 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 vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally based within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the 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 a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Yosemite Home Decor Aries 53 in.

Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area 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 produced from cast iron, but can also be made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the atmosphere. The best way to estimate the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is provided through a big glass window while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.electric wall fireplace
