Ancient fire pits were sometimes built from the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (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 casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

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 limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management problems because of the amount of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were 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 house. These fire pits were usually centered within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, and was constructed 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 into houses.Superior MPD Merit Plus Direct Vent Gas Fireplace Video
Some fireplace components include a blower that transfers 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 enhanced with the use of a fireback, a piece of metal which sits behind the flame 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 concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the atmosphere. The ideal 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 for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the first heat is provided through a large glass window while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next 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 sufficient to guarantee a constant room temperature.lennox fireplaces
