Ancient fire pits were sometimes built in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an 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 coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a wall or roof. These could be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer place at the 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 also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were utilized 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. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

FAQs about electric fireplaces
On the exterior there is 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 serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell good, but it's 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 gas or wood or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems because of the amount of moisture they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside 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. Together with the Industrial Revolution, came large 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 that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.Shop Real Flame 40.9in W 4,780BTU White Wood Corner LED Electric Fireplace with Media Mantel Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower 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 made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. The best method to estimate the output signal of a fireplace is in case you detect 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 at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplaces electric
