Ancient fire pits were sometimes built from the floor, in caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out through a wall or roof. These could be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer place on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead 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 still placed on supplying quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficacy, based upon the design.Historically they have been utilized for heating a home, 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.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.

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 businesses have laws limiting these types of fireplaces. Additionally, there are air quality control issues because of the amount of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a room, allowing more people to collect around it.

Many defects 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 performers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two components, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Indoor Fireplaces Stone Faux Fireplace at The Home Depot Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased with the use 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 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 air. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the initial heat is offered through a large glass while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.faux fireplace
