Ancient fire pits were sometimes constructed from the floor, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out through a wall or roof. These can be put against stone walls, rather than 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 problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead 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 placed on supplying quality stone. Stone fireplaces now have been a symbol of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they have been utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used 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 often 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 functions to keep rainwater from the exterior 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 standard 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 like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
In the United States, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality management problems due to the quantity of moisture they release in the room air, and oxygen sensor 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 is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than modern fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the period 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 level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Real Flame Frederick TV Stand with Electric Fireplace Reviews Wayfair Video
Some fireplace units 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 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 made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the first heat is provided through a large glass window while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. 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 its surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.tv stand fireplace
