Historical fire pits were sometimes built from the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation 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 climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These can be put against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer place on top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time were a sign of prosperity, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, based upon the design.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used 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's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws limiting these types of fireplaces. There are also air quality management issues due to the amount 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 from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a room, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.PUREGLOW STANFORD OAK FINISH FIREPLACE SURROUND SURROUNDS Fires2u.com Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also 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, intended to warm the air. The ideal way to estimate the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is offered through a large glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace surrounds
