Ancient fire pits were sometimes built from the ground, within caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or irritating smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These could be put against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber 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 a longer place at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple layouts with little unnecessary ornamentation. From 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 have been a symbol of wealth, which to a degree remains the notion today.A fireplace is a construction made from 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 change in heat efficiency, depending on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's 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 in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. 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 counties have laws limiting these types of fireplaces. There are also air quality management issues due to the quantity of moisture they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials 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 surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Dimplex Bailey 66Inch Electric Fireplace Media Console With Glass Embers Espresso GDS25G Video
Some fireplace units incorporate a blower which transports 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 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 complex 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, designed to heat the air. The ideal way to gauge the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the initial heat is offered through a big glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace media console
