Ancient fire pits were sometimes constructed from the floor, within caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out through a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, since they were more expensive to develop and maintain.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 basement and venting out a lengthier place on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now have been a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficacy, based upon the design.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 other flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, where the projecting 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 at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas 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.
In the United States, several states and local businesses have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems because of the quantity of moisture that they discharge into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally centered within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Walker Infrared Electric Fireplace Entertainment Center in Cherry 25MM5326C245 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 area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet 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 although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace entertainment center
