Ancient fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it out through a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were 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 which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the foundation for modern fireplaces.
Instead it depended 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 still placed on providing quality stone. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized 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 is frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, some states and local counties have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control problems due to the amount of moisture that they discharge in the room air, and oxygen sensor 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 exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a space, 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 that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of two components, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Majestic Products: Fireplaces Home Hearth Video
Some fireplace units 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 decrease heating load. Fireplace efficiency can also be increased 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 made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplaces
