Historical fire pits were sometimes built from the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out via a wall or roof. These can be placed against rock 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 issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier area on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, based on the design.Historically they were used for heating a home, 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 (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 frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which soaks up all but the 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 various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can 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, several states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality control issues because of the amount of moisture that they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.1500W Embedded Insert Electric Quartz Infrared Fireplace Heater Flame w/Remote eBay Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the atmosphere. The best method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is offered through a big glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace heater
