Ancient fire pits were sometimes built in the ground, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced hazardous or irritating smoke within the dwelling.Fire pits grown into raised 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 flame burned with all 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 throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, since they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major 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. He also enhanced the airflow by pulling air from a basement and venting a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that 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 threat. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the USA, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control issues due to the amount of moisture they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and port all exhaust gasses to 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 more fire pits compared to 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 space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into homes.Best 25+ Stone veneer fireplace ideas on Pinterest Stone fireplace mantles, Stone fireplace Video
Some fireplace units include a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal that 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 although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The ideal way to gauge the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.stone fireplace
