Ancient fire pits were sometimes built in the ground, within caves, or in the center 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 hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where a open flame burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These can be placed against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer place on top. At the later 18th century, Count Rumford made 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 amount of radiant heat projected to the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to a degree is still the idea 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 for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (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 is frequently a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric 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, several states and local businesses have laws limiting these types of fireplaces. There are also air quality management issues due to the quantity of moisture that they release in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses to the exterior of the structure.

As time passes, 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 functioned as a gathering place inside the house. These fire pits were usually centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Sequoia Fireplace Insert, Wood Stove Insert by Kuma Stoves Video
Some fireplace components include a blower that transfers 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 is also increased with the use 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 manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to estimate the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass window while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.wood fireplace inserts
