Ancient fire pits were sometimes constructed in the ground, in caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated 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 coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out through a wall or roof. These can be placed against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
Instead it depended 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 still placed on supplying quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficacy, based on the plan.Historically they were used for heating a home, 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 often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality management problems because of the amount of moisture they discharge in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.Napoleon GVF36N Vent Free Fireplace Fireplaces at Hayneedle Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the air 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 sheet of metal which sits behind the flame 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 concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is offered through a big glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.napoleon fireplaces
