Ancient fire pits were sometimes built in the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside through 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 in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, as they were expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced 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 at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant warmth projected into 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 deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now were a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical 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 United States, some states and local businesses have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control problems due to the quantity of moisture they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than 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 inside the home. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed 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 burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Southern Enterprises Redden Corner Electric Fireplace TV Stand eBay Video
Some fireplace units 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 piece of metal which 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 complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The best method to gauge the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively 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 can also be altered 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 often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a large glass window while the fire is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.corner electric fireplace tv stand
