Ancient fire pits were sometimes built in the floor, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer place on top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
Instead it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made from 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 have been utilized for heating a home, 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.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues due to the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits than modern fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were usually centered within a room, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was where the fire burnt, and was constructed 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 to homes.1000+ ideas about Stone Veneer Fireplace on Pinterest Stone Veneer, Stone Fireplaces and Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower 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 manufactured from stainless steel. Efficiency is a complex notion though 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. The best method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.stone fireplace
