Ancient fire pits were sometimes built in the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or annoying smoke within the dwelling.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 all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside via a wall or roof. These could be placed against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. 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 use immediately, however, as they were expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time 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 made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been used 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's frequently a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local businesses have laws limiting these kinds of fireplaces. There are also air quality management problems due to the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.25+ best ideas about Whitewash Brick Fireplaces on Pinterest Brick fireplace mantles, Update Video
Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that sits behind the fire 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 complex concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to gauge the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example 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 high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is offered through a large glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This heat 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. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.brick fireplace
