Historical fire pits were sometimes constructed from the ground, within caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside through a wall or roof. These can be placed against stone walls, rather than taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem 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 conveniently. They didn't come into general usage instantly, however, as they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation 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 relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a sign of wealth, which to a degree remains the idea today.A fireplace is a structure 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 space. Modern fireplaces change in heat efficiency, based 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 (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, 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 route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
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 can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues due to the amount of moisture that they discharge in the room atmosphere, 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 completely sealed from the area that is heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, in addition to 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 collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Lyemance EZ Open Damper Handle Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be 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 notion although 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. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a large glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace damper
