Historical fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt 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 snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These can be put against rock walls, instead of taking up the middle of the space, and this allowed 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 feasible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the top. At the later 18th century, Count Rumford made 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 heat projected to the space. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated 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 significant health risk. The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary 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 home. These fire pits were usually based within a room, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of 2 parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.Artesian White Cabinet 28quot; Infrared Firebox 28WM426T401 28II042FGL ClassicFlame Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means 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 made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80 percent 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 window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace mantle
