Ancient fire pits were sometimes constructed in the ground, within caves, or at the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside via a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a longer area at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
Instead it depended on simple layouts with little 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 at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based on the plan.Historically they have been used 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 (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

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 kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues due to the quantity of moisture they release into the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses to the outside of the structure.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.72quot; Fresno White Electric Media Fireplace Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the atmosphere. The best method to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified 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 large glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.media fireplace
