Ancient fire pits were sometimes constructed from the floor, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or annoying smoke inside the house.Fire pits developed into elevated 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 fire burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against stone walls, rather than taking up the center of the room, and this allowed 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 faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that 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 place at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple layouts 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 providing quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, depending upon 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 alternative flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
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 businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues due to the amount of moisture they discharge into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.Pleasant Hearth Arrington Fireplace Screen and BiFold TrackFree Glass Door Reviews Wayfair Video
Some fireplace units incorporate a blower that transports 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 is also increased with the use of a fireback, a sheet of metal that 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 though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to gauge the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a big glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.glass fireplace screen
