Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback 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 had a centrally located hearth, where a open flame burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it out via a ceiling or wall. These can be put against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's design is the foundation for modern kitchens.
Instead it relied 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 at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they were 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 is frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several 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 control problems due to the amount of moisture they discharge into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually centered within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers 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 materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Fireplace Wikipedia Video
Some fireplace units include 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 is also increased with the use of a fireback, a piece of metal which 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 concept though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. The best way to estimate the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a large glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace
