Historical fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout 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 prevent smoke from dispersing a room and vent it out via a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue 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 use immediately, 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 that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier place on very 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 out of the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now were a sign of prosperity, 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 that they create and also for heating a space. Modern fireplaces change in heat efficacy, based upon 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 other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesManufactured 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 electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems because of the amount of moisture they release 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 area that's heated, and vent all exhaust gasses into the outside of the structure.
Fireplace Mantels and Surrounds
Over time, 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 have been used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally centered within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.TOP 20 FIREPLACE Decorating Ideas Video
Some fireplace components incorporate a blower which transfers 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 increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two stages. During the first stage the first heat is provided through a big glass window while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace ideas
