Ancient fire pits were sometimes built from the floor, in caves, or at 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 irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire 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 rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out through a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were devised 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 give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, 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. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer area on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected to 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 depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now were a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, based upon the design.Historically they have been used for heating a dwelling, 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.

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 outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater 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. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems due to the quantity of moisture that they discharge in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that's heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that was 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 dimensions.
From the 1800s most new fireplaces were composed of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Best 25+ Corner fireplace tv stand ideas on Pinterest Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to estimate the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively 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 improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the first heat is offered through a big glass while the flame is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.corner fireplace tv stand
