Ancient fire pits were sometimes constructed from the floor, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it out through a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection room 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. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone 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, where the emphasis was placed on providing quality gems. Stone fireplaces now were a sign of wealth, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been utilized 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, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
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 threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues because of the quantity of moisture they discharge into the room atmosphere, and oxygen detector and carbon dioxide 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 port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to houses.26 best Fireplaces images on Pinterest Fireplace ideas, Corner fireplace layout and Country homes Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although 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 heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.electric fireplace
