Ancient fire pits were sometimes built in the floor, 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 early indoor fire pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits developed into elevated 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 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 throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out through a wall or roof. These can be put against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage 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 airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a longer place on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, depending on 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 often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside 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, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces.

Many defects were found in ancient fireplace designs. The most famous fireplace performers 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 quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 components, the surround and the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.WoodBurning Fireplace Inserts Jotul Wood Burning fireplace insert.

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 lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the flame 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 notion although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.wood burning fireplace insert
