Historical fire pits were sometimes built from the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open flame burned with all 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 snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out via a ceiling or wall. These could be put against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.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 also made it possible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, 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. 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 cellar and venting a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with small 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 stone. Stone fireplaces now were a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, based on the design.Historically they have been used 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 other flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, 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 route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves 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 metallic liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local counties have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management issues due to the quantity of moisture they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary 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 space, allowing more people to gather 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 has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Outdoor Fireplace Ideas Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air 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 sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The best way to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified 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 large glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace ideas
