Historical fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented 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 possible to put fireplaces in multiple rooms in buildings handily. 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. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into 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 a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they have been utilized 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 other flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen 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's often a corbeled brick crown, in which the projecting courses of brick function 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 in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
In the United States, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality management issues because of the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert 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 thought to bring a cozy ambiance to homes.Crafty Texas Girls: Paint Colors {Crafty Texas Girls} Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal which 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 although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to heat the air. The best way to estimate the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively 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 boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is provided through a large glass window while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.painted brick fireplace
