Ancient fire pits were sometimes built from the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke inside the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burned with all 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 rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These could be put against stone walls, rather than taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, as they were more expensive to build and maintain.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 basement and venting out a lengthier area at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the foundation for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a sign of wealth, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they have been 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 alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger 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 cap or crown.
Organizations such as 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.Kinds of fireplacesArtificial fireplaces are made with 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, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture they discharge into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They have been 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 usually based within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been 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 2 parts, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Southern Enterprises Redden Corner Electric Fireplace TV Stand FI9392 Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which 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 complex concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first phase the first heat is provided through a big glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.corner fireplace tv stand
