Ancient fire pits were sometimes built from the ground, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned 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 covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These can be placed against stone walls, rather than taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from 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 place fireplaces in multiple 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 room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a sign of prosperity, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. 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 bar, 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, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
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 restricting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management 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 have been fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.How Should I Light my Fireplace Properly? Littman Bros Video
Some fireplace components include a blower which transfers 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 enhanced by means of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex notion 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, designed to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a large glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.how to light a gas fireplace
