Ancient fire pits were sometimes built in the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it out through a ceiling or wall. These could be put against stone walls, rather than taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer area at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of 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.
Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, depending upon the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there is often a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior 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 soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.

In the USA, some states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management issues because of the amount of moisture they release in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were 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 usually based within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.Home Decorators Collection Avondale Grove 59 in.

Some fireplace units include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.electric fireplace
