Ancient fire pits were sometimes built from the floor, within caves, or in the center of a hut or home. Evidence of prehistoric, 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 dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These could be placed against stone walls, rather than taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they have been used for heating a home, 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 casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor integrated 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 could pose a significant health risk. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture they release in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.Scalloped McLean Hearth Rug Wayfair Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal that sits behind the fire 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 notion 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 heat the air. The ideal method to gauge the output of a fireplace is in case you detect you are 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 at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much 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 system in two stages. During the first phase the initial heat is offered through a large glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace rugs
