Ancient fire pits were sometimes built from the floor, within caves, or at 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 flame pits was that they produced toxic and/or annoying smoke inside the house.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms 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 feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, since they were 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. The 18th century saw two important developments in the history of fireplaces. 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 cellar and venting out a lengthier place on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it depended on simple designs with little 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 gems. Stone fireplaces now were a sign of wealth, which to some degree is still 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 also for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they have been 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 crane (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 frequently 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 exterior of the chimney; rain in the chimney is a much greater difficulty 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 crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.3 Ways to Light a Gas Fireplace wikiHow Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to estimate the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve 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 air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.how to turn on gas fireplace
