Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside via a ceiling or wall. These could be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.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 possible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general usage instantly, however, since they were more expensive to develop and maintain.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 efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time were a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local businesses have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems due to the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most famous fireplace performers 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 lit, with a emphasis on the quality of the substances used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.392 best images about fireplace ideas on Pinterest Fireplace mantels, Mantels and Mantles Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means 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 can also be made from stainless steel. Efficiency is a complex concept though 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 heat the atmosphere. The ideal way to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much 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, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass window while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace mantel ideas
