Historical fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with 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 rain and snow 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 ceiling or wall. These could be placed against rock walls, rather than taking up the center 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 problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, as they were more expensive to build and maintain.

In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the basis for modern fireplaces.

Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, based upon the design.

Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality control issues due to the quantity of moisture that they release in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses to the outside of the structure.

AccessoriesFor the inside, common in recent Western cultures comprise grates, fireguards, log boxes, andirons, bark baskets, along with fire dogs, all which cradle fuel and accelerate burning. A grate (or fire grate) is a framework, usually of iron bars, to maintain fuel to your fire. Heavy metallic firebacks are occasionally used to catch and re-radiate warmth, to protect the back of the fireplace, and as decoration. Fenders are low metallic frames set before the fireplace to include embers, soot and ash.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.

By the 1800s newest fireplaces were composed of 2 components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.

Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.

Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace gas inserts
