Historical fire pits were sometimes built from the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside through a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.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.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick function as a drip route 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 at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality control issues due to the quantity of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for heat 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 based within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed of 2 parts, the surround and the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.The Yellow Cape Cod: Extreme Fireplace Makeover Video
Some fireplace components include 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 enhanced 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 manufactured from stainless steel. Efficiency is a complex 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, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to estimate the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example 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 air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is offered through a big glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.tv over fireplace
