Ancient fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a ceiling or wall. These could be put against rock walls, rather than taking up the middle of the room, and this allowed smaller chambers 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 outside. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, as they were more 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 major developments in the history of fireplaces. 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 basement and venting out a longer area at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the design.Historically they were 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 other flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen 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's frequently a corbeled brick crown, where the casting courses of brick function 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 exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local businesses have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues due to the amount of moisture they discharge into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was 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 believed to bring a cozy ambiance into homes.TV Stand Entertainment Center Media Console Shelves Electric Fireplace Black New Video
Some fireplace components include a blower which transfers 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 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 made from cast iron, but are also made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to gauge the output of a fireplace is if you notice you're 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 requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the first heat is provided through a big glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace media console
