Ancient fire pits were sometimes constructed from the ground, within caves, or in the middle 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 generated hazardous or irritating smoke inside the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with all 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 snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a wall or roof. These could be placed against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to develop and maintain.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. In addition, he improved the airflow by pulling air from a basement and venting out a longer area at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now have been a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, based on the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems because of the quantity of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits than contemporary 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 house. These fire pits were usually centered within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of two components, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.Anywhere Fireplace Oasis Table Top Indoor / Outdoor Fireplace Fireplaces at Hayneedle Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in 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 which 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 complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is in case you notice 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 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a large glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second stage. 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 ensure a constant room temperature.anywhere fireplace
