Ancient fire pits were sometimes built from the floor, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out through a wall or roof. These could be placed against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, since they were more 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 efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic 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 like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of 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 couple of types 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 United States, some states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management issues because of the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.SpectraFire 36 in.

Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be 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 can also be made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The best way to gauge the output signal 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 can reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two phases. During the first phase the first heat is offered through a large glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace inserts electric
