Historical fire pits were sometimes built in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, however, as they were expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol 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 the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the 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 could pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control issues because of the quantity of moisture they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a space, 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 kind of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burned, and was built 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 homes.Gas Fireplace Inserts Recalled by Jotul North America Due to Electrical Shock and Burn Hazards Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider just 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 toaster, and has done so as the 15th century. The ideal method to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is offered through a large glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace insert
