Historical fire pits were sometimes constructed in the ground, in caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed during 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 devised to stop smoke from spreading through an area and vent it out through a wall or roof. These could be placed against stone walls, instead of taking up the center of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, since they were expensive to develop and maintain.The 18th century saw two important 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 cellar and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's layout is the foundation for modern fireplaces.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now were a sign of wealth, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, based on the design.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where 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 from the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A few 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 either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems because of the amount of moisture that they release in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Fireplace, Soft Jazz Rain Romantic Date Night Inside YouTube Video
Some fireplace units incorporate a blower that 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 increased 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 complicated concept although 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. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal way to estimate the output of a fireplace is if you detect 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 necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace romantic
