Historical fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside through a ceiling or wall. These can be placed against rock walls, rather than taking up the middle of the space, and this enabled 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 provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, since they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the foundation for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made of 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 efficiency, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is often 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 outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems because of the amount of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either 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 compared to contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials 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 insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Best 25+ Fall fireplace decor ideas on Pinterest Fall mantle decor, Fire place mantel decor Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in 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 can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The best way to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have 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 much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the first heat is offered through a large glass 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 many hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace mantel decor
