Ancient fire pits were sometimes constructed from the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be placed against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, 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 airflow and venting system. 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. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now were a sign of prosperity, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficiency, based upon the plan.Historically they were utilized 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 alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the amount of moisture that they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were usually based within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.Real Flame Devin Indoor Gel Fireplace in Dark Espresso 1220DE Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal that 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 complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to gauge the output signal of a fireplace is if you detect you are 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 such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding 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 large fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is offered through a big glass while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.gel fireplace
