Ancient fire pits were sometimes constructed in the floor, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or irritating smoke inside the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open flame burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.

Also throughout 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 put against rock walls, rather than taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, since they were more 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 important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the basis for modern kitchens.

Instead it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, based on the design.

Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting 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 from the outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for 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. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management problems because of the quantity of moisture that they discharge into the room air, and oxygen sensor 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 is heated, and vent all exhaust gasses to the outside of the structure.

AccessoriesFor the interior, common in current Western cultures comprise grates, fireguards, log boxes, andirons, pellet baskets, along with fire dogs, all of which cradle gas and quicken burning. A grate (or flame grate) is a frame, usually of iron bars, to retain fuel for a fire. Heavy metallic firebacks are occasionally utilized to capture and re-radiate warmth, to protect the rear of the fireplace, and as decoration. Fenders are low metal frames set in front of the fireplace to include embers, soot and ash.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually based within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their dimensions.

From the 1800s newest fireplaces were composed of two components, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.

Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also 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 produced from cast iron, but are also made 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, intended to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat up or down.

Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually 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 window while the fire is burning. During this time the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace inserts
