Ancient fire pits were sometimes built in the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out via a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible 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 more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time have been a symbol of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were used 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 alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick act as a drip route 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 at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
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 significant health threat. The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, several states and local counties have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues because of the quantity of moisture they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a room, 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, requiring a standardization of fireplaces. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Corinth Wall or Corner TV Stand with 23 Electric Fireplace Premium Oak Pricefalls.com Marketplace Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the fire 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 complicated notion though 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 since the 15th century. The best way to gauge 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 rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass window while the flame is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.corner electric fireplace tv stand
