Ancient fire pits were sometimes built in the ground, within caves, or in 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 inside the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a lengthier area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a symbol of wealth, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic 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 crane (utilized in kitchen and laundry 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 is frequently 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 from the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional 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 could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues because of the amount of moisture they release into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the outside of the structure.

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

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.Walker Edison Furniture Company 58 in.

Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means 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 can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass while the flame is burning. In this time period 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 just offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.black fireplace tv stand
