Ancient fire pits were sometimes constructed in the ground, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These could be placed against rock walls, rather than taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage immediately, however, since they were more expensive to develop 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 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 out a longer area at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces at this time were a sign of wealth, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, 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 outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor integrated 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 could pose a significant health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of 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 few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, several states and local counties have laws limiting these types of fireplaces. Additionally, there are air quality management problems because of the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses into the exterior of the structure.

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

Many flaws were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Dimplex Montgomery Espresso Corner Electric Fireplace Media Console GDS251057E 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 decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.dimplex electric fireplaces
