Ancient fire pits were sometimes built from the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burnt with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside through a wall or roof. These can be placed against stone walls, rather than taking up the middle of the room, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to develop 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 improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer area on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces now were a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, based on the design.Historically they were utilized for heating a home, 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 (used in kitchen and laundry 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's 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 cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management issues because of the quantity of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of this 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 a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the 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 add a cozy ambiance to houses.Hot Fireplace Design Ideas HGTV Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the atmosphere. The best way to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a large glass window while the flame is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace designs
