Ancient fire pits were sometimes constructed from the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out through a ceiling or wall. These could be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, since 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. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to contain 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 plan.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen 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's frequently 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 hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides 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 good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
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 gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these types of fireplaces. There are also air quality management issues due to the amount of moisture they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that's 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 visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally based within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of two components, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.48quot; black media fireplace Big Lots Snuggle Up By The Fireplace Video
Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be 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 are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a big glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.big lots fireplace
