Historical fire pits were sometimes built in the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow 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 put against rock walls, rather than taking up the middle of the space, 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 reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, since 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 on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design improved greatly the quantity of radiant warmth projected into the room. Rumford's design is the basis for modern kitchens.
Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, based on the design.Historically they have been utilized 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 (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood 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 electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws restricting 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 amount of moisture that they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many flaws were found in ancient 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 colored, with an emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Best 25+ Small electric fireplace ideas on Pinterest Small electric heater, Electric fireplace Video
Some fireplace units 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 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 made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.small electric fireplace
