Ancient fire pits were sometimes built in the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned with all the smoke rising to the port 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 devised to stop smoke from dispersing a room and vent it outside via a ceiling or wall. These could be put against rock walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room 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 out a lengthier place at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they were 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 alternative flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. A few 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 businesses have laws limiting these kinds of fireplaces. There are also air quality control problems due to the quantity 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 liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses to the outside 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 contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of 2 components, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.IronStrike Performer C210 Wood Burning Fireplace Insert USA Made Cast Iron EPA eBay Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively 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 boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the first heat is provided through a big glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.wood burning fireplace insert
