Ancient fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, as 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 room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer place on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's design is the basis for modern fireplaces.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing 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 made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

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 hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality control issues because of the quantity of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been 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 purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually based within a space, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been 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 size.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to houses.48quot; Corner Fireplace TV Stand Black Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased 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 made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.corner fireplace tv stand
