Historical fire pits were sometimes built in the ground, in 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 early indoor fire pits was that they produced toxic and/or irritating smoke inside the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open flame burnt with the smoke rising to the vent 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 stop smoke from dispersing an area and vent it out through a wall or roof. These could be put against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.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 possible to give 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, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the foundation for modern fireplaces.
Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they were used for heating a home, 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 bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can 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, electrical 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 types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management issues because of the quantity of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the 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 an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Fireplaces On Sale Aifaresidency.com Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The best method to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is offered through a large glass window while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplaces for sale
