Historical fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the center of the room, and this enabled 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 outside. They made it possible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage 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 which greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place on 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 out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, based on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from 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 most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could 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.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws limiting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They have been 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 usually based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was 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 into houses.Chelsea Anywhere Fireplace Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased by means 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 complicated concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to gauge the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly 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 for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the first heat is offered through a big glass window while the fire is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.anywhere fireplace
