Ancient fire pits were sometimes built from the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burnt with all 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 snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a wall or roof. These could be put against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. 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 cellar and venting a lengthier area at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. Rather 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 placed on providing quality stone. Stone fireplaces at this time have been a sign of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control problems due to the quantity of moisture that they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits than modern fireplaces.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were composed of two components, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.SpectraFire 36 in.

Some fireplace units include a blower which transfers 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 is also enhanced with the use 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 complicated concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the first heat is provided through a large glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplace insert
