Historical fire pits were sometimes built from the floor, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an 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 coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside through a wall or roof. These could be put against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.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 possible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually based within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.SpectraFire 39 in.

Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use 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 are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, 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 if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the first heat is offered through a large glass while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace inserts
