Ancient fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These can be put against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably 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 didn't come into general usage 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. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple designs 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 gems. Stone fireplaces now have been a sign of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.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. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.

In the United States, several states and local counties have laws restricting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems because of the amount of moisture they release in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the add. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into homes.Salem Wood Mantel Shelves Fireplace Mantel Shelf MantelsDirect.com Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made 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, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output signal of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wood fireplace mantels
