Historical fire pits were sometimes constructed from the ground, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out through a ceiling or wall. These can be put against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be heated.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 possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer place on 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 from the construction. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now were a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been used 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 (utilized in laundry and kitchen 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's frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides 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 different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality control issues because of the quantity of moisture they release 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 completely sealed from the area that's heated, and port all exhaust gasses to the exterior of the structure.

It was smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest 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 insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Home Decorators Collection Chestnut Hill 68 in TV Stand Electric Fireplace with Sliding Barn Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced 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 complicated concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The best method to estimate the output signal 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, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is provided through a large glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace tv stands
