Historical fire pits were sometimes built from the floor, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open fire burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a wall or roof. These can be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put 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.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was 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 of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, depending on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were composed of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.Southern Enterprises Newburgh 45.5 in.

Some fireplace units incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a big glass window while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.faux fireplace
