Ancient fire pits were sometimes built in the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These could be placed against stone walls, instead of 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 mostly fixed the problem of fumes, more reliably venting smoke out. 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 use immediately, however, since they were more expensive to develop 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 enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer area at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a sign of prosperity, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few 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 propane fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues because of the amount of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than modern fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Real Flame DiNatale 50 in.

Some fireplace components 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 is also increased by means of a fireback, a piece of metal that 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 notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The best way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the first heat is provided through a big glass while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.wall mount electric fireplace
