Ancient fire pits were sometimes built in the floor, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside via a wall or roof. These can be placed against rock walls, rather than taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use 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 improved the airflow by pulling air from a basement and venting out a longer place at the 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 quantity of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now have been a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
In the USA, several states and local businesses have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control problems due to the amount of moisture they discharge into the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses into 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 fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were usually centered within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. 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 colored, with an emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were composed of two components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Best 25+ Stone veneer fireplace ideas on Pinterest Stone fireplace mantles, Stone fireplace Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece 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 complicated 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 heat the air. The ideal method to gauge the output of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase 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 heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.stone fireplaces
