Historical fire pits were sometimes built from the ground, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out through a ceiling or wall. These could be put against stone walls, rather than taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage instantly, however, since they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer place on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the basis 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 relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to 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 is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far larger difficulty 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 crown or cap.

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 restricting these types of fireplaces. They need to be suitably 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 detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.DIY Wood Beam Mantel Video
Some fireplace units include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced with the use 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 manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. The ideal way to gauge the output of a fireplace is in case you detect you're 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 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may 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 altered fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is offered through a large glass window while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wood fireplace mantels
