Ancient fire pits were sometimes built from the ground, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open fire burned with all the smoke climbing into the port 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 throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out via a wall or roof. These can be put against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were devised 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 provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage immediately, however, since they were more expensive to develop 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. He also improved the airflow by pulling air from a cellar and venting out a lengthier area at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of prosperity, which to some degree remains 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 that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending on the plan.Historically they were 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 alternative flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some 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 different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems due to the quantity of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were made up of 2 components, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Interior.

Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass window while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.brick fireplace
