Historical fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out through a ceiling or wall. These could be placed against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully 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 conveniently. They didn't come into general use instantly, however, since they were expensive to build and maintain.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 basement and venting a longer place on top. At the later 18th century, Count Rumford made a fireplace using 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 warmth projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple designs with small 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 at this time have been a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the design.Historically they have been used for heating a home, 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.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside 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, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems due to the quantity of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.TV Stands with Electric Fireplace: Amazon.com Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The ideal way to gauge the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is offered through a big glass while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.amazon electric fireplace
