Historical fire pits were sometimes built from the ground, in 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 flame pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside through a wall or roof. These could be placed against stone walls, instead of taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, since they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer area at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now were a symbol of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were used for heating a dwelling, 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. A fireplace might have the following: a foundation, 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as 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 good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality control issues due to the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are security 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 exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Whalen Media Fireplace Console for TVs up to 55quot;, Dark Cherry Walmart.com Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means 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 can also be manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output of a fireplace is if you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is offered through a large glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace tv stand walmart
