Ancient fire pits were sometimes built from the floor, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a ceiling or wall. These could be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased 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 that greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant heat projected to the space. 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 also deflected unnecessary ornamentation. Rather it depended 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 placed on providing quality gems. Stone fireplaces now have been a symbol of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, based upon the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared 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 great, but it's not great for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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 USA, several states and local businesses have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture that they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally based within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Dimplex Electraflame Fieldstone Natural Stone Free Standing Electric Fireplace eBay Video
Some fireplace components incorporate a blower which 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 sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The ideal way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the first heat is offered through a large glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.free standing fireplace
