Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke rising to the vent 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.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage immediately, however, since they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. 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 a longer place at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the basis for modern fireplaces.
Rather it depended 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 placed on supplying quality stone. Stone fireplaces at this time have been a sign of wealth, which to some degree remains the idea 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, depending upon the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, several states and local counties have laws limiting these types of fireplaces. There are also air quality management issues due to the quantity of moisture they release into 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 in the place that's 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 modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, 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 2 components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.50quot; Electric Fireplace Wall Mounted White w/Heat 400 sq ft Touchstone 80002 eBay Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal which sits behind the flame 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 complicated concept though with open hearth fireplaces. Most efficiency tests consider only the effect 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 toaster, and has done so since the 15th century. The ideal way to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the first heat is provided through a large glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.wall mount fireplace
