Ancient fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists 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 grown into raised hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burned with 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 snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a wall or roof. These can be put 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 problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier area on very top. In 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 building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the foundation for modern kitchens.
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 stone. Stone fireplaces now were a sign of prosperity, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the rain. Some 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 need to be properly sized to the area to be heated. There are also air quality management issues because of the amount of moisture that they discharge 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 area that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were usually centered within a space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers 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 an emphasis on the quality of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Best 25+ Hanging fireplace ideas on Pinterest Floating fireplace, Suspended fireplace and Bq Video
Some fireplace units 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 decrease heating load. Fireplace efficiency is also 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. The ideal way to gauge the output of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the initial 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 heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.hanging fireplace
