Ancient fire pits were sometimes built from the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or irritating smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a ceiling or wall. These could be put against stone walls, rather than taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general usage immediately, however, as they were more expensive to build and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design improved greatly the quantity 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 on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended on simple designs 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 now have been a symbol of prosperity, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, in which 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 from the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for wood or gas 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 United States, several 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 issues due to the amount of moisture they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are security 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.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of 2 parts, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.AKDY 23 in.

Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced 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 manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to estimate the output of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a large 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 fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplace inserts
