Ancient fire pits were sometimes constructed from the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a ceiling or wall. These could be placed against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, 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 airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier area at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also 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, where the emphasis was still placed on providing quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, based on the plan.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions 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, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

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 either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place 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 necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers 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 an emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Napoleon Ascent 42 Direct Vent Gas Fireplace Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured 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 is not, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the first heat is provided through a large glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth 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. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.direct vent gas fireplace
