Ancient fire pits were sometimes built from the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open flame burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside through a ceiling or wall. These can be put against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, since they were expensive to develop 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 room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier place at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that 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 to the space. Rumford's design is the basis for modern fireplaces.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry 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's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much larger difficulty 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 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 various studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with 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 either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality management issues because of the quantity 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 completely sealed in the place that's 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 compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a room, allowing more individuals to gather 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 renowned fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.Gas Fireplace Blower Fireplace Heat Exchanger Fireplace Fan Fireplace Blower Kit Video
Some fireplace components include a blower that 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 by means of a fireback, a piece of metal which 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 efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the air. The best method to estimate the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is provided through a large glass window while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace blower
