Ancient fire pits were sometimes constructed in the floor, in caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out via a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was 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 space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a symbol of wealth, which to a degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.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 may have the following: a foundation, 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's 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 out of the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the 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 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 businesses have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management issues due to the amount of moisture that they release into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. 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 colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Stonegate Polystone Electric Fireplace with Mantel 5115 BTU CSN4126FR eBay Video
Some fireplace components incorporate a blower which transfers 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 can also be increased with the use of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. The best method to gauge the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first stage the first heat is offered through a big glass while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric fireplace
