Ancient fire pits were sometimes constructed in the floor, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open flame burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These could 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 issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced 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 on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often 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 functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated 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 can pose a significant health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local counties have laws restricting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management issues due to the quantity of moisture that they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has changed 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, 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 ancient fireplace designs. The most famous fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.30+ Patio Designs, Decorating Ideas Design Trends Premium PSD, Vector Downloads 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 area and a decrease heating load. Fireplace efficiency can also be increased by means 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 are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve 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 altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is offered through a big glass window while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.outside fireplace
