Ancient fire pits were sometimes constructed in the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These could be put against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely 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 handily. They didn't come into general use instantly, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant warmth projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now were a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, depending on the plan.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, 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 function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much larger problem 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. A few chimneys have a spark arrestor incorporated into the crown or cap.

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 gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture that they discharge into the room air, and oxygen detector and carbon dioxide sensors are safety 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 to the outside of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burnt, and was constructed of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Electric Fireplace TV stand Heater Corner or Straight 32 38 44quot; Mantle Flat NEW eBay Video
Some fireplace components 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 increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to heat the air. The ideal way to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a big glass while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces with no 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.electric fireplace tv stand
