Ancient fire pits were sometimes constructed in the floor, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a wall or roof. These could be put against rock walls, instead of taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, since they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer area on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, based upon the design.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function 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 at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that divides up all but the rain. Some 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 different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, some states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality management problems due to the quantity of moisture that they discharge into the room atmosphere, 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 from the place that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of two parts, the surround and the insert. The encircle consisted 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 often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Gas Fireplaces Panorama P36 Kastle Fireplace Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece 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 made from stainless steel. Efficiency is a complicated notion although 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. The best way to estimate the output of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is offered through a large glass while the flame 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 second stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.regency fireplace
