Historical fire pits were sometimes built from the ground, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists 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 structures, 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 the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a wall or roof. These can be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely 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 put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, since 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 which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer area at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's frequently 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 serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control problems due to the amount of moisture that they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be 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 can also be manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace mantel decorating ideas
