Historical fire pits were sometimes constructed in the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burnt with the smoke climbing into the port 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.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out through a wall or roof. These could be put against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to develop 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 room for the fireplace that 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 area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the foundation 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, where the emphasis was still placed on supplying quality gems. Stone fireplaces now were a symbol of wealth, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they were 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 may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, 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 function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality control issues due to the amount of moisture they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.Wood Mantels for Fireplaces Custom Chalkville Video
Some fireplace units include a blower that 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 by means of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The ideal way to gauge the output of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.wood fireplace mantels
