Historical fire pits were sometimes built from the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a ceiling or wall. These could be put against rock walls, rather than taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace using 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 warmth projected into the space. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been used for heating a home, 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 (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which soaks up all but the rain. A few 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 significant health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
In the United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management issues due to the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and vent all exhaust gasses to 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 were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which was 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 dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.GAS WHITE SURROUND BLACK GRANITE MARBLE SILVER FIRE FIREPLACE SUITE LARGE 54quot; eBay Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. 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 since the 15th century. 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 relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.white fireplace
