Ancient fire pits were sometimes constructed from the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or annoying smoke inside the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where a open flame burned with the smoke climbing into the vent 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 during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the space, and this enabled smaller chambers 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 out. They made it possible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier area on very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces now were a sign of wealth, which to some 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 that they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management problems because of the amount of moisture that they discharge in the room air, and oxygen detector 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 outside of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat 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 centered within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Cambridge Metropolitan 56 in.

Some fireplace components include a blower that transfers 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 can also be enhanced 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 are also manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to gauge the output signal of a fireplace is in case you notice you're 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 such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.wall mount fireplace
