Historical fire pits were sometimes built in the floor, within 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 fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The 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 throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.

Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be placed against rock walls, rather than taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.

In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer area on top. In 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 improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.

Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the plan.

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

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act 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 at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.

Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture that they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses into the exterior of the structure.

AccessoriesA wide range of accessories are used with fireplaces, ranging between states, regions, and historical periods. For the interior, common in recent Western cultures comprise grates, fireguards, log boxes, andirons, pellet baskets, and fire dogs, all which cradle fuel and accelerate burning. A grate (or fire grate) is a frame, usually of iron bars, to retain fuel for a fire. Heavy metal firebacks are sometimes utilized to capture and re-radiate warmth, to safeguard the rear of the fireplace, and as decoration. Fenders are low metallic frames placed before the fireplace to contain embers, soot and ash.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their size.

From the 1800s most new fireplaces were composed of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.

Some fireplace units include a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which 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 notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. The best method to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.

Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the first heat is provided through a large glass while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.outdoor gas fireplace
