Historical fire pits were sometimes built from the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These can be put against rock walls, rather than taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were 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. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now were a sign of wealth, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been 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 bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside 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 traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.

In the USA, some states and local businesses have laws restricting 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 amount of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the exterior 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 heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more individuals to collect 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 famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround and the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Outdoor Fireplace Design Ideas HGTV Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air 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 sheet of metal which 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 notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces without a 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.outdoor fireplaces
