Ancient fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a ceiling or wall. These can be put against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which 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 lengthier area on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount 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 relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the plan.Historically they have been utilized 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.

On the exterior there's frequently a corbeled brick crown, in which the projecting 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 at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that 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 could pose a significant health threat. The EPA writes"Smoke may smell great, but it's 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 either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types 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 counties have laws limiting these kinds of fireplaces. There are also air quality control issues because of the quantity of moisture that they discharge in 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 in the place that is heated, and port all exhaust gasses into the exterior of the structure.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Pleasant Hearth 3/4 in. 24 in. 6Bar Steel Fireplace GrateBG7246M The Home Depot Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece 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 only the effect of heating of the air. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to gauge the output signal 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 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace grates
