Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open flame burnt with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer place at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time were a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the design.Historically they have been used for heating a dwelling, 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.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act 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 in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management problems because of the amount of moisture they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually centered within a room, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of two parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Best 25+ Double sided fireplace ideas on Pinterest Double fireplace, Two sided fireplace and Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal which sits behind the flame 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 efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to estimate the output of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is offered through a big glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.double sided fireplace
