Ancient fire pits were sometimes built in the ground, within caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burned with the smoke climbing into 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.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this enabled 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 reliably venting smoke out. 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 didn't come into general usage immediately, however, as 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. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room 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 lengthier area on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a sign of prosperity, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.

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 limiting these types of fireplaces. There are also air quality control problems because of the quantity of moisture that they discharge into 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 totally sealed from the place that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It had been smaller, more brightly lit, with a 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 parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.ProCom ProCom 32 in. Ventless Gas Firebox InsertPC32VFC The Home Depot Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced 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 produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The ideal method to gauge the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process 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 construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next stage. 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.gas fireplace inserts
