Ancient fire pits were sometimes built in the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised 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 that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's design is the foundation for modern fireplaces.
Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a symbol of prosperity, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, 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 act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that 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 significant health risk. The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, several states and local counties have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems due to the quantity of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were generally based within a room, allowing more people 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 famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.Electric Fireplace TV Stand Media Console Heater Entertainment Center Wood New eBay Video
Some fireplace components include a blower which 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 by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to warm the air. The ideal method to gauge the output signal of a fireplace is in case 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 though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass window while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.media fireplace
