Ancient fire pits were sometimes constructed from the ground, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire 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.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside through a ceiling or wall. These could be put against stone walls, rather than taking up the center of the room, and this allowed 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 out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a longer area on 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 from the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, based upon the design.Historically they have been utilized 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 foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used 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 frequently a corbeled brick crown, in which the projecting courses of brick function 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 in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

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 either 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 control issues because of the quantity of moisture that they discharge in the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large 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 was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.Gas Fireplace Repair Cost 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 area and a lower heating load. Fireplace efficiency is also enhanced 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. 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 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 boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a big glass while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.gas fireplace repair
