Ancient fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it out through a ceiling or wall. These can be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in 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 also made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, as 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 chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer 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 up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple layouts with small 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 at this time were a sign of wealth, which to a degree is still the notion today.A fireplace is a structure 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 change in heat efficacy, based upon the design.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

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 exterior walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesManufactured 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 electrical fireboxes.
In the USA, some states and local counties have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control problems because of the quantity of moisture that they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is 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 visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.20 Gorgeous TwoSided Fireplaces For Your Spacious Homes Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area 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 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 although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal method to gauge the output of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed 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 large fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.double sided fireplace
