Ancient fire pits were sometimes built from the ground, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These can be put 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 mostly 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 numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer area at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, based upon the plan.Historically they have been used 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. 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 throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function 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 problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws limiting these kinds of fireplaces. There are also air quality management problems because of the quantity of moisture that they release into 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 completely 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 transformed from one of necessity to one of interest. Early ones were fire pits than contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the home. 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 this period were the Adam Brothers. They perfected a style of fireplace design that was 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 most new fireplaces were composed of two components, the surround and the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Hawthorne 51In x 36In Wood Fireplace Mantel Surround Video
Some fireplace units include a blower that 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 can also be enhanced with the use of a fireback, a sheet of metal which 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 notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output signal of a fireplace is in case you detect 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 may also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wood fireplace surrounds
