Historical fire pits were sometimes built in the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burnt with all the smoke climbing into 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 invented to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These could be put against rock walls, rather than taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place on very 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 construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a sign of prosperity, which to some degree remains the idea today.A fireplace is a construction 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 change in heat efficiency, based on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace might 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 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 act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local counties have laws restricting these types of fireplaces. There are also air quality management problems because of the quantity of moisture they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on cold 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 space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of two components, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Header: New Stacked Stone Fireplace Surround Video
Some fireplace components incorporate a blower which 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 with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The best method to estimate the output signal of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the first heat is provided through a big glass window while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.stone fireplace surround
