Ancient fire pits were sometimes constructed in the floor, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or annoying smoke within the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burnt with all 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 rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out through a ceiling or wall. These can be put against stone walls, rather than taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also 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.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant warmth projected into the space. 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 rock and 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, in which the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used 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 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 alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few 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 kinds of fireplaces. Additionally, there are air quality control issues because of the amount of moisture they discharge into 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 totally sealed in the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of two parts, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.Paramount EF202MKIT Kampen Faux Stone Electric Fireplace Lowes Canada Video
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 space and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the first heat is provided through a big glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.lowes fireplace
