Historical fire pits were sometimes built from the ground, within caves, or in the center 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 produced hazardous or annoying smoke inside the house.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out via a wall or roof. These can be placed against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, 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 airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis 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 little unnecessary ornamentation. From 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 at this time have been a sign of wealth, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, depending on the plan.Historically they have been used for heating a dwelling, 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 laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, 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 exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater 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.

In the USA, some states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management issues due to the quantity of moisture that they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.Painted Brick Fireplace Makeover On Sutton Place Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. The best method to gauge 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 at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass window while the flame is burning. During this time the construction, constructed 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 just offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.painted brick fireplace
