Ancient fire pits were sometimes constructed in the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or annoying smoke inside the house.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where an open flame burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it out via a ceiling or wall. These can be put against stone walls, rather than taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which 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 room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Instead 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 still placed on providing quality gems. Stone fireplaces at this time were a sign of prosperity, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they have been utilized for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control issues due to the amount of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into 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 than modern fireplaces. They were 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 usually based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were made up of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.Limestone fireplaces and mantels by Architectural Limestone Inc. Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet 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 made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The ideal way to estimate the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.limestone fireplace
