Ancient fire pits were sometimes constructed in the floor, within caves, or at the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a ceiling or wall. These can be put against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from 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 also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen 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's frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the outside 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 compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated 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 could pose a substantial health risk. The EPA writes"Smoke may smell good, 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 gas or wood or retrofit with log inserts or electrical 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, some states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management issues because of the amount of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Aspen Infrared Electric Fireplace Mantel Package in Meridian Cherry 28WM1751C248 Video
Some fireplace components include a blower which 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 is also increased with the use of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. The best way to gauge the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. 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 altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large 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 phase the first heat is offered through a big glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.electric fireplaces
