Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out via a wall or roof. These can be placed against stone walls, instead of taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved 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 out of the building. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used 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 fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems because of the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and port 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 more fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers 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 colored, with an emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were composed of 2 components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Dimplex Concord Electric Fireplace Entertainment Center TV Stand eBay Video
Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal that sits behind the fire 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 notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the first heat is provided through a large glass window while the fire is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplace tv stand
