Historical fire pits were sometimes built in the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside through a wall or roof. These can be put against stone walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important 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 improved the airflow by pulling air from a cellar and venting a lengthier area on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been utilized 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 alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course 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 at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, several states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality control issues due to the quantity of moisture that they discharge into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on chilly 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 room, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of two parts, the surround and the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, 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 to houses.[10 Hours] Fireplace in the Study Video Audio [1080HD] SlowTV YouTube Video
Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also 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 are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output of a fireplace is if you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace video
