Historical fire pits were sometimes constructed in the floor, within caves, or in 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 generated hazardous or irritating smoke inside the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burnt with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout 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 rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were invented 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 handily. They didn't come into general usage immediately, however, as they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer area at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now have been a sign of wealth, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been 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 alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen 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, 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 functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater 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. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
In the USA, some states and local counties have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues because of the amount of moisture that they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, 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 heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which 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.
From the 1800s most new fireplaces were composed of two components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Rustic Electric Fireplaces I Portable Fireplace.comPortableFireplace.com Video
Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the first heat is offered through a large glass while the fire is burning. In this time the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.rustic electric fireplace
