Ancient fire pits were sometimes built from the ground, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burnt 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 coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be placed against stone walls, instead of taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were devised 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 give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, since they were expensive to develop 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 out a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace with 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 warmth projected into the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. 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 placed on supplying quality gems. Stone fireplaces at this time were a symbol of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were used for heating a home, 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.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like 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 great, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
In the United States, several states and local businesses have laws restricting these kinds of fireplaces. There are also air quality management problems because of the quantity of moisture that they discharge into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of 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 affirms, typically in wood, granite or marble. The fit was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Outdoor Stone Fireplace on Wood Deck Fireplaces and Firepits Pinterest Wood decks Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means 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 efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the first heat is offered through a large glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.outdoor fireplace
