Ancient fire pits were sometimes built from the floor, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These could be put against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier place on top. At 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 quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen 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, in which the casting courses of brick function 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 far greater problem in chimneys lined with impervious flue tiles or metal liners compared 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 such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured 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.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control problems because of the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most renowned 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 an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Sleek freestanding fireplaces designed by Malm Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet 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 although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The ideal way to estimate the output 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 requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the first heat is offered through a large glass while the flame is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.free standing fireplace
