Ancient fire pits were sometimes built in the floor, in caves, or in the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out via a ceiling or wall. These could be put against stone walls, instead of taking up the center of the space, and this allowed 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 outside. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't 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 a lengthier place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick act as a drip route 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 difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality management problems because of the quantity of moisture they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was 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 size.
From the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burnt, 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 add a cozy ambiance into houses.wibiworks.com Page 178: Transitional Interior Makeover with Flooring, Minimalist Family Room Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal which 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 complicated notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass window while the flame is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fake fireplace logs
