Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burnt 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 snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out through a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now were a sign of wealth, which to some 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 that they create and also for heating a room. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, 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 act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, some states and local counties have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues because of the amount of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind 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 newest fireplaces were made up of two parts, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.DIY: Fireplace Surround Transformation Jenna Burger Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal that 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 complicated concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal 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 relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace tile
