Historical fire pits were sometimes built from the floor, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had 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 snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These could be put against rock walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe in 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 made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as 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 important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place on top. In the later 18th century, Count Rumford designed 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 quantity of radiant warmth projected into the room. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now were a sign of prosperity, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, based on the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the 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 substantial health risk. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses 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 due to the quantity of moisture that they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They have been used for heat 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 collect around it.

Many defects were found in early fireplace designs. 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 a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of two parts, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Sophias: Flea Market Faux Fireplace Master Bedroom Update Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to 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 that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much 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, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a large glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fake fireplace
