Ancient fire pits were sometimes built in the ground, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires is present 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 elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be placed against stone walls, rather than taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, since they were more 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. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up 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.
Rather it relied 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 still placed on providing quality stone. Stone fireplaces at this time were a sign of wealth, which to a degree remains 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 space. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood 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 United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been 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 exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers 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 an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was built 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 houses.Direct Vent Gas Fireplace eBay Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the flame 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 although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as 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 rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is provided through a large glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.direct vent gas fireplace
