Ancient fire pits were sometimes built in the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.

Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside through a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this allowed 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 faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage instantly, however, as they were more expensive to build and maintain.

In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. 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. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern kitchens.

The Aesthetic movement of the 1870s and 1880s took on a more traditional 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, where the emphasis was placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, depending upon the design.

Historically they were used 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 other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home 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 projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger difficulty 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. Some chimneys have a spark arrestor integrated into the cap or crown.

Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not great 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 electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.

In the USA, some states and local businesses have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management problems because of the quantity of moisture they release in 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 area that is heated, and vent all exhaust gasses into the outside of the structure.

AccessoriesA wide assortment of accessories are used with fireplaces, which range between states, regions, and historical periods. For the interior, common in current Western civilizations include grates, fireguards, log boxes, andirons, pellet baskets, along with fire puppies, all of which cradle fuel and accelerate burning. A grate (or fire grate) is a framework, usually of iron bars, to maintain fuel to your fire. Heavy metallic firebacks are occasionally used to catch and re-radiate heat, to protect the back of the fireplace, and as decoration. Fenders are low metal frames placed in front of the fireplace to include embers, soot and ashes. For fireplace tending, tools comprise pokers, bellows, tongs, shovels, brushes and instrument racks. Other wider accessories can consist of log baskets, companion sets, coal buckets, cabinet accessories and much more.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.

By the 1800s most new fireplaces were made up of 2 components, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.

Some fireplace components include a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the fire 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 effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The best way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.

Most elderly fireplaces have a comparatively low efficiency rating. 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 altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace video
