Ancient fire pits were sometimes constructed from the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated 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 port in the roof. Louvers were developed throughout the Middle Ages to allow 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 spreading through an area and vent it outside through a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers 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 outside. 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.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
Rather it depended 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 stone. Stone fireplaces at this time have been a sign of prosperity, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.

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 either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management problems due to the quantity of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burnt, and was built 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 to houses.Dimplex Strata Linear Wall Mount Electric Fireplace DWF1205TR Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the air. The ideal way to gauge the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a large glass while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wall mounted fireplace
