Ancient fire pits were sometimes constructed in the floor, within 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 early indoor flame pits was that they generated toxic and/or annoying smoke inside the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burned with all the smoke rising to the vent 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 outside through a wall or roof. These can be placed against rock walls, instead of taking up the middle of the room, 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 reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern kitchens.
Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time were a sign of prosperity, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, 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 functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these kinds 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 into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety 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 outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Fireplace Logs Natural Gas Vented Dual Burner 18 50000 BTU CVS303 Chimney Flue eBay Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that 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 complex concept though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The best method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is offered through a large glass window while the fire is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.natural gas fireplace
