Ancient fire pits were sometimes built from the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer place on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the amount 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 traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it depended on simple layouts 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 gems. Stone fireplaces at this time were a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, based on the plan.Historically they have been used for heating a dwelling, 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 (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves 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 metal liners than with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated 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 significant health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
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 gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management problems due to the amount of moisture that they discharge into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to 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 usually based within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most famous 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 a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 components, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Electric Fireplace Clearance: Amazon.com Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the first heat is offered through a large glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.amazon electric fireplace
