Ancient fire pits were sometimes built in the ground, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been 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's frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the exterior 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 problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell great, but it's 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 wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, several states and local counties have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems due to the quantity of moisture that they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were 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 people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Sheridan Infrared Rolling Electric Fireplace White GLF500250 Pleasant Hearth Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in 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 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 just the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 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 high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is offered through a big glass window while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.electric fireplace heater
