Historical fire pits were sometimes built from the floor, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside 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 warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. 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 immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces at this time were a sign of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, based on the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

In the USA, several states and local counties have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues due to the quantity of moisture they release in the room air, 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 completely sealed from the place that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to 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 inside the home. These fire pits were usually centered within a room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Brick Outdoor Fireplace Vizimac Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a piece 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 complex concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to estimate the output of a fireplace is in case 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 for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is offered through a big glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.outside fireplace
