Ancient fire pits were sometimes constructed in the floor, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open flame burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a wall or roof. These can be put against rock walls, instead of taking up the center of the space, and this allowed smaller rooms 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 outside. They made it feasible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage 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. The 18th century saw two important 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. He also enhanced the airflow by pulling air from a cellar and venting a lengthier place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design 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. Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were utilized for heating a dwelling, 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 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 outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the most violent 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 threat. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems because of the amount of moisture that they release in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the area 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 requirement to one of interest. Early ones were fire pits than contemporary fireplaces.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of 2 components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.fireplace remodels ideas Scroll down for a photo of what this fireplace looked like before LBJ Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion 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, designed to heat the atmosphere. The best way to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much 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, enabling an efficient heating system in two phases. During the first stage the first heat is provided through a big glass while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth 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. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace remodel
