Ancient fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in structures, 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 all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside via a wall or roof. These could be put against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting 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. He also enhanced the airflow by pulling air from a basement and venting a longer area at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of wealth, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been used 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.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks 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 could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could 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.
In the United States, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems due to the amount of moisture that they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of 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 served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the 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 add a cozy ambiance to homes.Lowes Gas Fireplace Shop Procom 32000 Btu Vent Free Gas, Lowes Vent Free Fireplace Mccmatric Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet 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 concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The best method to estimate the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a large glass while the fire is burning. During this time the structure, 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 only provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.lowes gas fireplace
