Ancient fire pits were sometimes constructed from the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside via a ceiling or wall. These could be placed against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant heat 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 rock and also deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (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, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues due to the amount of moisture that they release in the room atmosphere, and oxygen sensor and carbon dioxide 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 to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than modern 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 generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been 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 dimensions.
By the 1800s most new fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Pearl Mantels 618 Crestwood MDF Fireplace Mantel Shelf in White Video
Some fireplace units 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 can also be increased by means of a fireback, a sheet of metal that sits behind the fire 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 efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace mantel shelf
