Ancient fire pits were sometimes built from the ground, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a wall or roof. These could be put against rock walls, rather than 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 faithfully venting smoke out. They made it possible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality management issues due to the quantity of moisture they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the time 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 a emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.Fireplace Mantels Mendota Hearth Video
Some fireplace components 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 enhanced by means 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 can also be made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just 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 of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning 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 inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a big glass window while the fire is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace mantel kits
