Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, as they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they were utilized 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 alternative flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (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's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management problems due to the amount of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house.

Many defects were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.DecorFlame Electric Space Heater Fireplace with 38quot; Mantle, Oak Walmart.com 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 space and a lower heating load. Fireplace efficiency is also 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 produced from cast iron, but are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The best 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, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the first heat is provided through a big glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplace walmart
