Ancient fire pits were sometimes built in the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout 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 put against stone walls, rather than taking up the middle of the space, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From 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 now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been utilized 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 other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.

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 limiting these kinds of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

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

Many flaws were found in early fireplace designs. The most renowned 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 a emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.How to Build a Fireplace Mantel With Reclaimed Timbers howtos DIY Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet 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 made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. The best way to gauge the output signal of a fireplace is if you detect you are 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 improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the first heat is offered through a big glass while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.how to build a fireplace
