Ancient fire pits were sometimes built from the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open flame burned with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside via a wall or roof. These can be put against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. 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 basement and venting out a longer area on top. In the later 18th century, Count Rumford made a fireplace using 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 to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and deflected unnecessary ornamentation. Rather it relied 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 supplying quality gems. Stone fireplaces now have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon 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 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 out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few kinds 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, some states and local businesses have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality management problems due to the quantity of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with a 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 as well as the add. 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 frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.GoldenVantage Wall Mount Electric Fireplace Reviews Wayfair Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced 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 made 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 just the effect of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to gauge the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the initial heat is offered through a big glass window while the flame is burning. During this time 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 just offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric wall fireplace
