Ancient 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 irritating smoke inside the dwelling.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where a open flame burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside via a wall or roof. These can be put against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves 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 compared with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for 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 gel, liquid propane, bottled gas or natural gas. In the USA, several states and local counties have laws restricting these kinds of fireplaces. There are also air quality management issues due to the amount of moisture they release in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind 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, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Dimplex Brayden OptiMyst Wall Mount Electric Fireplace BBK20R Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as 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 large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.wall mounted fireplace
