Historical fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout 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 placed against stone walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer place at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern fireplaces.
Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to some degree remains the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, based on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often 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 hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues because of the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
From 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, marble or granite. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Monessen Chesapeake Ventless Gas Fireplace w/Remote ControlPropane eBay Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use 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 can also be made from stainless steel. Efficiency is a complicated notion though 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 warm the atmosphere. The best method to estimate the output of a fireplace is if you detect you are 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 at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.ventless gas fireplace
