Ancient fire pits were sometimes built from the floor, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke within 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 located hearth, where a open fire burned with all 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 snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out through a ceiling or wall. These can be put against stone walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a longer area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to a degree remains 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 they create and also for heating a room. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were 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, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some 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 could pose a substantial health risk. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesManufactured 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 electrical fireboxes.
In the USA, several states and local businesses have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control issues because of the amount of moisture that they discharge into 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 in the place that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.Shop Chimney Free 42in W 4,600BTU Cherry Electric Fireplace with Thermostat and Remote Control Video
Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal which sits behind the flame 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 notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. The ideal way to estimate the output of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass window while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.lowes fireplace
