Historical fire pits were sometimes constructed from the floor, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where a open flame burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a ceiling or wall. These can be placed against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer place on top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout 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 placed on providing quality stone. Stone fireplaces at this time have been a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been used for heating a home, 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 might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, 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 serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the 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, several states and local businesses have laws restricting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality management issues because of the amount of moisture they release in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually based within a space, allowing more people 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 colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.How to Brighten Up a Room with a Tile Fireplace Makeover Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet 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 made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to estimate the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the first heat is provided through a big glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace makeover
