Historical fire pits were sometimes built from the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a wall or roof. These can be placed against rock walls, rather than taking up the middle of the space, and this allowed smaller chambers 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 feasible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier area on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a sign of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they have been utilized for heating a home, cooking, and heating water for domestic and laundry uses.

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

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management issues because of the quantity of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble.

Some fireplace components include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to heat the air. The ideal method to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is offered through a large glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.corner gas fireplace
