Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside through a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer area on very 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 out of the building. The shallow design also 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 conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now were a symbol of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is 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 cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which 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 substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood 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 USA, some states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture they release in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the outside 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 have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually based within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.3 Panel Metal Fireplace Screen Folding Doors Bronze Finish Hearth Cover Antique eBay Video
Some fireplace units incorporate a blower that transports 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 that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to heat the atmosphere. The best method to estimate the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered 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 large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass window while the flame is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace screen
