Historical fire pits were sometimes constructed from the ground, within caves, or in the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier place on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it depended 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 still placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (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 is often 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 hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the most violent rain. A few 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. In the USA, some states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues because of the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are 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 outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Regency Gas Insert Horizon HRI6E Gas Insert The Fireplace Club Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece 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 efficacy tests consider just the impact 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 ideal way to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.regency fireplace
