Historical fire pits were sometimes built from the floor, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/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 great hall typically needed a centrally situated hearth, where an open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside via a ceiling or wall. These could be placed against rock walls, rather than taking up the center of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it depended 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 supplying quality stone. Stone fireplaces now were a sign of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, based upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, in which the projecting 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 out of the exterior of the chimney; rain at 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.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws restricting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management problems because of the amount of moisture that they discharge into the room air, 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 in the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of this time 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 materials used in their construction, as opposed to their size.
From 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 affirms, usually in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with ornamental tiles.

Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced 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 are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass while the fire is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric wall fireplace
