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 fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside through a ceiling or wall. These could be placed against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in 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 also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier place at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple layouts 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 supplying quality stone. Stone fireplaces now were a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as 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 good, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds 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, some states and local businesses have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues due to the amount of moisture they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in 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 requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Dimplex Tate OptiMyst Wall Mount Electric Fireplace TAH20R Video
Some fireplace units incorporate a blower which transfers 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 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 complicated concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The best way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most older 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 may also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the first heat is offered through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wall mounted fireplace
