Historical fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated 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 great hall typically needed a centrally located hearth, where a open flame burned with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside 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 chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, since 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 important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a longer place on very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to a degree remains the idea today.A fireplace is a construction 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 room. Modern fireplaces vary in heat efficacy, depending upon the plan.Historically they have been utilized for heating a dwelling, 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 crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger problem 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. A few chimneys have a spark arrestor incorporated into the cap or crown.

In the United States, several states and local counties have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems due to the amount of moisture that they discharge into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of two components, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.CorLiving E0001EPF Electric Fireplace Insert Lowes Canada Video
Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal which sits behind the flame 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 notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the first heat is provided through a big glass window while the fire 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 second phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplace insert
