Historical fire pits were sometimes built from the ground, within 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 hazardous or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame 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 coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out through a wall or roof. These can be put against rock walls, rather than taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to build and maintain.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 cellar and venting a lengthier place at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock 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, where the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of wealth, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical 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 limiting these kinds of fireplaces. There are also air quality control problems because of the quantity of moisture they discharge in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either 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.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were usually based within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to houses.Wallmount Fireplace from Arkiane Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The best way to estimate the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the first heat is offered through a large glass while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.wall mounted fireplace
