Ancient fire pits were sometimes built in the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open flame burned 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 rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside via a wall or roof. These can be put against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, as they were expensive to build 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 efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, 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 exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the amount of moisture they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally based within a space, allowing more individuals 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 has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Pearl Mantels Celeste Fireplace Mantel Shelf eBay Video
Some fireplace units include a blower which 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 can also be increased 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 produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. 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 may also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass window while the fire is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace mantel shelf
