Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open flame burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a wall or roof. These could be placed against rock walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a lengthier area on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time have been a sign of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been 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. 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 pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where 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 outside of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, several states and local counties have laws restricting these types of fireplaces. There are also air quality management problems due to the amount of moisture they discharge into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for warmth on cold days and nights, in addition to 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 collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Cartwright Mission Oak Corner / Flat Wall GEL FUEL FIREPLACE TV Stand FG9285 SEI Video
Some fireplace components incorporate a blower that transports 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 is also increased by means of a fireback, a piece of metal that 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 concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. 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 estimate the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the first heat is offered through a big glass while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.corner fireplace
