Ancient fire pits were sometimes constructed from the floor, within caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow 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 spreading through a room and vent it outside via a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer area at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's layout is the foundation for modern fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending upon the plan.Historically they have been used 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 may 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 room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality control problems due to the amount of moisture they release into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.custom fireplace surround Traditional Family Room DC Metro by FA Design Build Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal method to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the first heat is provided through a big glass while the flame is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace hearth
