Ancient fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame 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 coated so rain and snow would not enter.
Additionally 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 could be put against rock walls, rather than taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier place at the very top. In 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 building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending on 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 alternative flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. 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 kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems due to the amount of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.DIY Faux Fireplace Entertainment Center: Part One Blesser House Video
Some fireplace components incorporate a blower that transfers 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 enhanced by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal method to estimate the output of a fireplace is if you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may 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 system in two phases. During the first phase the initial heat is offered through a big glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.faux fireplace mantel
