Historical fire pits were sometimes built from the floor, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open flame burned 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 during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a wall or roof. These can be put against rock walls, rather than taking up the center 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 feasible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. 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 made to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, depending on the design.Historically they were utilized 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 other flue allows exhaust to escape. A fireplace may have the following: a foundation, 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 chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick function 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 compared with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management issues because of the quantity of moisture they discharge into 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 totally sealed in the area that is heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the intent behind 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 chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance into homes.1400W Free Standing Insert Electric Fireplace Firebox Heater Flame Wood Remote Video
Some fireplace components include a blower that 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 enhanced with the use of a fireback, a piece of metal that sits behind the flame 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 notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the atmosphere. The best method to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the first heat is offered through a big glass window while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.free standing fireplace
