Ancient fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where an open fire burned with 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 would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out through a wall or roof. These could be placed against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
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 providing quality stone. Stone fireplaces now have been a sign of wealth, which to a degree is still 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 that they create and for heating a space. Modern fireplaces vary in heat efficacy, based upon the design.Historically they were used 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 other flue allows exhaust to escape. 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, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared 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 like 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.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, several 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 problems because of the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually centered within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Wakefield Linear Wall Mount Electric Fireplace DWF1318 Video
Some fireplace units include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is offered through a large glass window while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wall mount electric fireplace
