Ancient fire pits were sometimes constructed from the ground, in caves, or in the center 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 toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out through a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. 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 providing quality gems. Stone fireplaces at this time were a sign of prosperity, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficiency, based upon the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, 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 USA, some states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management issues because of the quantity of moisture that they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been 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 transformed from one of necessity to one of interest. Early ones were more fire pits than 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 inside the house. These fire pits were usually based within a room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s newest fireplaces were composed of two components, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Shop Matte Black Electric Fireplace 25inch TV Stand Free Shipping Today Overstock 6030031 Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased 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 made from cast iron, but are also made from stainless steel. Efficiency is a complex concept though 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 heat the air. The best method to estimate the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is provided through a big glass window while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.black fireplace tv stand
