Historical fire pits were sometimes built in the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally during 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 put against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. From 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 at this time were a sign of prosperity, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves 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 metal liners than with the standard masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame 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 propane fuel sources. In the United States, several states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management problems due to the quantity of moisture they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually centered within a room, allowing more individuals 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 which 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 most new fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Corinth Infrared Electric Fireplace Media Console in Vintage Cherry 23DE1447C233 Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in 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 made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal way to estimate the output of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and can 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 process in two stages. During the first phase the initial heat is provided through a big glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace media console
