Historical fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where a open fire burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a ceiling or wall. These could be put against rock walls, rather than taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer area at the top. At 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 building. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied 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 still placed on supplying quality stone. Stone fireplaces at this time have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there is often 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 serves to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
In the United States, some states and local counties have laws limiting these kinds of fireplaces. There are also air quality control issues because of the amount of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and port all exhaust gasses to 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 compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers 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 lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Real Flame Kipling 54 in.

Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The ideal way to estimate the output of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding 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 usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is offered through a large glass while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.white fireplace
