Historical fire pits were sometimes constructed from the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the 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 out of the construction. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a symbol of wealth, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficiency, depending on the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, where the casting 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 far greater problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides 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 various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture they release in 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 completely sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

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

Many flaws were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Pearl Mantels Shenandoah Traditional Fireplace Mantel Shelf Fireplace Mantels Surrounds at Video
Some fireplace units include a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to warm the air. The best way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass window while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace mantel
