Ancient fire pits were sometimes constructed from the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These can be placed against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to develop 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 place at the top. In the later 18th century, Count Rumford designed a fireplace using 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 quantity of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made of 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 design.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's 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 hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic 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.
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 risk. The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture they release into the room air, and oxygen sensor and carbon dioxide 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's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually based within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 parts, the surround and the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.25+ best ideas about Fireplace parts on Pinterest Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The best way to estimate the output of a fireplace is if you detect you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the first heat is provided through a big glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace parts
