Ancient fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside via a wall or roof. These can be put against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier area on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design is the basis for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. In 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 prosperity, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they have been used 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 other flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip course 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 far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality management issues due to the quantity of moisture they release in the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s newest fireplaces were made up of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Fire glasses – Machprinciple.com Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced by means 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 are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace glass
