Historical fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside through a ceiling or wall. These could be put against rock walls, rather than taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, however, as they were expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier place at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather 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 providing quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.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 might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

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 hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the most violent rain. A few 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 significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management issues due to the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually centered within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an 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 two components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.Real Flame Tracey Grand Infrared Black Electric Fireplace 8720EBLK Real Flame Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be 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 can also be made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The best method to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have 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 can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.black electric fireplace
