Ancient fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside via a wall or roof. These can be put against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more 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 which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier area 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 construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of wealth, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they have been utilized 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. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

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 hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at 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 cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues because of the quantity 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 is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits than modern fireplaces. They have been 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 people to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Best 25+ Double sided fireplace ideas on Pinterest Double fireplace, Tvs for dens and Bathroom Video
Some fireplace units include a blower which transports 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 is also increased by means 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 can also be manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess 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 designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.double sided fireplace
