Historical fire pits were sometimes built from the ground, in caves, or in the middle 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 toxic and/or annoying smoke inside the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned 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 rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a ceiling or wall. These can be placed against stone walls, instead of taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, 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 (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. There are also air quality management problems because of the quantity of moisture that they release in 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 place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Object moved 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 space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the fire 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 although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The best way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a large glass window while the fire 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 next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.black fireplace tv stand
