Ancient fire pits were sometimes constructed from the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burnt with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a wall or roof. These can be put against rock walls, rather than taking up the center of the space, and this allowed 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 possible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, since they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier area on top. In the later 18th century, Count Rumford made a fireplace with 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 amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now were a symbol of prosperity, which to some 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 the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, based 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 other 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, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, several states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture that they discharge in the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They have been 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 usually centered within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed 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 often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Essex White Electric Fireplace by Dimplex Wolf and Gardiner Wolf Furniture Video
Some fireplace components incorporate a blower which 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 increased 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 produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. 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 detect you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass window while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.dimplex fireplace
