Historical fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where an open flame burned with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a ceiling or wall. These can be put against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a sign of wealth, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem 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 integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture that they release into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.32quot; ClassicFlame Spectrafire+ Curved Electric Fireplace Insert 32EF023GRA Video
Some fireplace components incorporate a blower which 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 sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The best way to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a big glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.electric fireplace insert
