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 exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open fire burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside via a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room 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 longer place on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, based on the design.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen 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 casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds 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. Additionally, there are air quality control problems due to the quantity of moisture they release in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place 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 necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were generally based within a room, allowing more people to gather around it.

Many defects 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 the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Best 25+ Big lots electric fireplace ideas on Pinterest Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal which sits behind the fire 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 concept though 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're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is offered through a big glass window while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.big lots fireplaces
