Ancient fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a 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 rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage 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 airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber 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 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 the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a sign of wealth, which to a degree is still the idea today.A fireplace is a construction made of 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 efficacy, depending on the plan.Historically they were used for heating a home, 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. 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 pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip course 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 at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides 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 is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality management issues due to the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses into 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 contemporary fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.25+ best ideas about Small electric fireplace on Pinterest Black electric fireplace, Electric Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. The ideal method to gauge the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a large glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.small electric fireplace
