Ancient fire pits were sometimes built from the floor, in caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or annoying smoke inside the house.Fire pits developed into raised hearths in buildings, but ventilation 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 climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, as they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
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 layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

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 outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at 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 crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws restricting these kinds of fireplaces. There are also air quality control problems due to the amount of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.56 Rectangle Burgundy Oriental Fireplace Rug Northline Express 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 decrease heating load. Fireplace efficiency can also be increased by means 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 though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the atmosphere. The best method to estimate the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a big glass while the fire is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace rugs
