Historical fire pits were sometimes constructed in the floor, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These can be put against stone walls, rather than taking up the center of the space, and this allowed 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 outside. They made it possible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of prosperity, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor incorporated 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 could pose a substantial health risk. The EPA writes"Smoke may smell good, 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 either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, several states and local businesses have laws restricting these types of fireplaces. There are also air quality control issues because of the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary 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 usually based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been 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 newest fireplaces were made up of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Dimplex 33quot; MultiFire XD PlugIn Electric Insert Logs PF3033HL Dimplex Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just 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 as the 15th century. The best method to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.dimplex electric fireplace insert
