Ancient fire pits were sometimes constructed in the floor, in caves, or at the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the basis 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, where the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a symbol of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip route 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 at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
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 significant health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management problems due to the amount of moisture they discharge into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Best 25+ Diy outdoor fireplace ideas on Pinterest Backyard fireplace, Backyard kitchen and Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece 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 notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. 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 since the 15th century. The best way to gauge the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.diy outdoor fireplace
