Historical fire pits were sometimes built in the floor, in caves, or at the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside via a wall or roof. These can be put against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended 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 placed on providing quality gems. Stone fireplaces now were a symbol of wealth, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficiency, depending upon the design.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell good, but it's 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 either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local counties have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems due to the amount of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of two components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.Home Decorators Collection Edison 40 in.

Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that 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 concept though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to heat the air. The ideal way to estimate the output of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly 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 altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the first heat is provided through a large glass window while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace console
