Ancient fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open flame burned 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 covered so rain and snow would not enter.
Also 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 rock walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible 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 usage immediately, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces at this time were a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been utilized 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 other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick act 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 much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, several states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The surround 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 ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.FK18 Heatilator Wood Fireplace Blower Dual Fan Kit Single Speed Factory OEM new eBay Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased 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 made 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 air. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive 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 fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace parts
