Ancient fire pits were sometimes constructed from the ground, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside through a wall or roof. These can be put against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly 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 numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were more 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 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 improved the airflow by pulling air from a cellar and venting a longer place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the idea 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 also for heating a room. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local businesses have laws limiting these types of fireplaces. There are also air quality control problems because of the amount of moisture that they discharge in the room air, and oxygen detector and carbon monoxide 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 exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually centered within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this 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 substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Majestic Products: Fireplaces Home Hearth Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal which sits behind the fire 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 concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method 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 relatively low efficiency rating. Standard, contemporary, weatherproof 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 inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a big glass window while the fire is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.gas fireplaces
