Ancient fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside via a wall or roof. These could be put against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier area on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at 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 rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric 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 limiting these kinds of fireplaces. There are also air quality control issues because of the amount of moisture they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than modern 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 defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality 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 as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the 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 believed to bring a cozy ambiance into homes.25 Stunning Fireplace Ideas to Steal Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced 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 can also be made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. The ideal way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the first heat is provided through a big glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace surround ideas
