Historical fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it out through a ceiling or wall. These could be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now have been a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
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 threat. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood 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 electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems due to the amount of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of this 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 substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.How to Build a New Fireplace Surround and Mantel HGTV Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. The ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn 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 system in two phases. During the first stage the first heat is provided through a big glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.how to build a fireplace
