Historical fire pits were sometimes built in the ground, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside through a ceiling or wall. These can be put against stone walls, rather than taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, since they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer place at the top. In 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 quantity of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. From 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 now were a symbol of prosperity, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. 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 must be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the amount of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of two components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burned, and was constructed 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 houses.1000+ ideas about Fireplace Cover on Pinterest Fire place decor, Faux mantle and Faux fireplace Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced 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 are also made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The ideal way to gauge the output signal of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the initial heat is provided through a big glass window while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace cover
