Ancient fire pits were sometimes constructed in the floor, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside through a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, as they were expensive to develop 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 major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier 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 from the construction. The shallow design also improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the basis for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made of 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 efficiency, depending on the design.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior 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 metal liners compared with the standard masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated 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 USA, some states and local counties have laws restricting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management problems because of the quantity of moisture that they release in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either 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.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was 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 made up of two parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.DecorFlame Electric Fireplace Space Heater with 44quot; Wide Mantle Walmart.com Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use 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 are also made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm 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 are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the first heat is provided through a large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.walmart fireplace
