Ancient fire pits were sometimes built in the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or annoying smoke inside the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly 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 put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, since they were expensive to build 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 chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the space. 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 rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, based on the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality control problems due to the amount of moisture that they discharge into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and vent all exhaust gasses to the outside of the structure.

By the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into houses.Creative Outdoor Fireplace Designs and Ideas Video
Some fireplace units include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal that sits behind the fire 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 complicated notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the atmosphere. The best way to gauge 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 score. 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 can also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is provided through a big glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.patio fireplace
