Ancient fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out through a ceiling or wall. These can be put against rock walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the quantity of radiant warmth projected into the room. 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 deflected unnecessary ornamentation. Instead it depended on simple layouts with little 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 gems. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated 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, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues due to the quantity of moisture that they discharge in the room atmosphere, 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 place that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were usually centered within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two parts, the surround and the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, 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 add a cozy ambiance to houses.11 Brick Fireplace Makeovers Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that sits behind the flame 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 complex concept though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal way to gauge the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively 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 boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the initial heat is provided through a large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.painted fireplace
