Ancient fire pits were sometimes built from the floor, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor fire pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where an open flame burned with all the smoke rising to the port 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 devised to stop smoke from spreading through a room and vent it out via a ceiling or wall. These could be put against rock walls, rather than taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, as 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 room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance 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 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 pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

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 serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, several states and local businesses have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control problems due to the quantity of moisture that they discharge into 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 area that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a room, allowing more individuals to gather around it.

Many flaws 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 had been smaller, more brightly lit, with a 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 components, the surround and the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Dimplex Electraflame Fieldstone Natural Stone Free Standing Electric Fireplace eBay Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although 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 heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output signal 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 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the first heat is offered through a big glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.free standing fireplace
