Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or annoying smoke inside the house.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open flame burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be heated.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 feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier place on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to some degree is still 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 that they create and for heating a space. Modern fireplaces change in heat efficiency, based on the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
In the USA, several states and local counties have laws restricting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management problems because of the quantity of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually centered within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers 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, instead of their size.
By the 1800s most new fireplaces were composed of two components, the surround and the add. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.Real Flame Silverton Electric Fireplace in White Video
Some fireplace components include a blower that transports 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 piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. 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 since the 15th century. The best way to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is offered through a large glass while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace video
