Ancient fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burned with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out through a wall or roof. These can be placed against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.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 possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer area on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. 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 stone and deflected unnecessary ornamentation. Rather 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 placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen 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 frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger difficulty 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 cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local businesses have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems due to the amount of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been 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.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Shop Pleasant Hearth Colby Sunlight Nickel Small CabinetStyle Fireplace Doors with Smoke Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use 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 made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The ideal method to estimate the output signal of a fireplace is in case you notice 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 at least 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 high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass window while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.glass fireplace doors
