Ancient fire pits were sometimes built in the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside via a wall or roof. These can be put against stone walls, instead of taking up the middle of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer area on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces at this time have been a symbol of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the 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 could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could 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.
In the USA, several states and local businesses have laws restricting these types of fireplaces. There are also air quality control issues due to the amount of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home.

Many flaws were found in ancient fireplace designs. The most renowned 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 colored, with a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into homes.Dimplex 23quot; Standard Electric Fireplace Insert/Log Set DFI2309 / DFI23096A Dimplex Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece 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 made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to estimate the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive 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 construction, 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 just offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.dimplex electric fireplace
