Historical fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These can be put against rock walls, rather than taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, as they were more 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 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 improved the airflow by pulling air from a basement and venting a lengthier place at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected into the room. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a sign 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 used for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, based upon the design.Historically they were 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 crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. Some 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's not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local businesses have laws limiting these types 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 they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses into the exterior of the structure.

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

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which 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 dimensions.
From 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, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Real Flame White Chateau Corner Electric Fireplace Contemporary Indoor Fireplaces portland Video
Some fireplace components incorporate a blower that transports 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 is also enhanced by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. The ideal way to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass window while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.indoor fireplace
