Historical fire pits were sometimes constructed from the floor, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a wall or roof. These could be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe in 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 did not come into general use instantly, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a longer area on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting 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 exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
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 good, but it is not good for you.Kinds of fireplacesManufactured 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 couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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. In the United States, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces.

The fit was fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Galley Faux Stone Electric Fireplace Wayfair Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect 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 as the 15th century. The ideal way to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.stone electric fireplace
