Ancient fire pits were sometimes constructed from the ground, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open flame burnt 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 would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside through a wall or roof. These could be placed against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general usage instantly, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer place on top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected into the space. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a sign of wealth, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they were utilized for heating a dwelling, 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. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions 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 rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. 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 suitably sized to the area to be heated. There are also air quality management problems because of the quantity of moisture they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were 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 usually centered within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Sinclair Electric Fireplace TV Stand in Aged Cherry 2591848 Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept 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 heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first phase the initial 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 warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace tv stands
