Ancient fire pits were sometimes constructed in the floor, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out through a wall or roof. These can be put against stone walls, rather than taking up the center of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer area on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now were a sign of wealth, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, based on the design.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip route 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 much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. There are also air quality management issues because of the quantity of moisture they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses into the exterior of the structure.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Simple and Sophisticated Fireplace Mantel Ideas Video
Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the first heat is provided through a large glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace mantel ideas
