Historical fire pits were sometimes constructed from the floor, within caves, or in the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame 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 holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These can be placed against rock walls, rather than taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in 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 made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation 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. Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now have been a symbol of prosperity, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they have been 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 other flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems because of the amount of moisture they discharge into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses into the exterior 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.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.17 Best ideas about Outdoor Fireplaces on Pinterest Backyard fireplace, Outdoor patios and Video
Some fireplace components incorporate 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 enhanced by means 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 are also made from stainless steel. Efficiency is a complicated concept though 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 warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning 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 altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the first heat is provided through a large glass window while the flame is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.outdoor fireplaces
