Historical fire pits were sometimes built from the floor, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These could be placed against stone walls, rather than taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, as they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the basis for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might 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 bar, home 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, where the casting courses of brick function as a drip course 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 at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

In the USA, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture they discharge into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Southern Enterprises Rosedale Corner Electric Fireplace TV Stand FI9345 Video
Some fireplace components include 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 is also increased with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 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 may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. 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 heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.corner electric fireplace tv stand
