Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where an open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer place on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the foundation for modern fireplaces.
Rather it depended on simple layouts with little unnecessary ornamentation. From 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 were a symbol of wealth, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated 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 can pose a significant health threat. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems due to the amount of moisture they release into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the place that is 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 visual interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Best 25+ Double sided fireplace ideas on Pinterest Double fireplace, Two sided fireplace and 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 lower heating load. Fireplace efficiency can also be increased by means 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 manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to gauge the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is provided through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.double sided fireplace
