Ancient fire pits were sometimes built in the ground, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a 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 coated so snow and rain 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 can be put against rock walls, rather than taking up the middle of the space, and this allowed smaller rooms 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 outside. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, as they were expensive to develop and maintain.The 18th century saw two major 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 a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, based on the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house 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, where 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 out of the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which soaks up all but the most violent rain. A few 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 substantial health risk. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management issues because of the amount of moisture they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in 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 requirement to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually based within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design that 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.
From the 1800s newest fireplaces were made up of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Southern Enterprises Narita Espresso w/Electric Fireplace TV Stand eBay Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge 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, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as 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 large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is offered through a large glass while the fire 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 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 ensure a constant room temperature.fireplace tv stand
