Historical fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where a open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during 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 stop smoke from spreading through a room and vent it outside through a wall or roof. These could be put against rock walls, rather than taking up the middle of the room, and this allowed smaller chambers to be warmed.Chimneys were invented 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 also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design improved greatly the amount of radiant heat 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 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 of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, 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 may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized 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, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some 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 various studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality management issues due to the amount of moisture that they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by 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 purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of two components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Dimplex Sussex Electric Fireplace White at Hayneedle Video
Some fireplace components incorporate a blower that transports 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 can also be enhanced with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to gauge the output of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the first heat is offered through a large glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.white electric fireplace
