Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burned 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 devised to prevent smoke from spreading through an area and vent it out via a wall or roof. These could be put against rock walls, rather than taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible 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 use 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 efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the design.Historically they were utilized for heating a home, 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 (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home 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, where the projecting courses of brick act as a drip route 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 much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality control problems due to the amount of moisture they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from 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 necessity to one of visual interest. Early ones were 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 home. These fire pits were generally centered within a space, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.WALL MOUNTED CURVED GLASS ELECTRIC FIREPLACE FIRE HEATER SLIM DESIGN FLICKER eBay Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased 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 though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal method to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass window while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wall mounted fireplace
